Synopsis
How to Train Your Dragon (2003)
The first book in the series follows Hiccup as he captures a dragon as a rite of passage and attempts to train him so that he will not be exiled from Berk, as is its tradition for young Viking boys on this island. Led by their teacher, Gobber the Belch, Hiccup manages to catch a small dragon, whom he names Toothless, and attempts to train it through his own methods. The Viking students are told to read a book called 'How to Train Your Dragon' by Professor Yobbish, but the book was found to have only one page and was therefore unhelpful. The Viking students must have their dragons trained before the Thor'sday Thursday Celebration in order to become proper Vikings. During this celebration, Toothless offends another dragon and a fight ensues between all the dragons. As this is seen as failure to train the dragons correctly, all the boys are sentenced to exile, but allowed to stay one night while a storm rages. During the storm, two Sea Dragons are washed up on the shore of the island and one eats the other, and seems a threat to the Vikings. Hiccup is chosen to negotiate with the dragon, who has eaten one of the other dragons. However, the dragon, who calls himself the Green Death, says he is going to kill all the Vikings. While the village elders argue over how to attack the Green Death, Hiccup, the boys and their dragons start a fight between the Green Death and the other sea dragon, the Purple Death, resulting in Hiccup nearly being swallowed and having to be rescued by Toothless, killing both sea dragons in the process. Hiccup and Toothless become heroes because of their bravery.
How to Be A Pirate (2004)
Hiccup finds the coffin of Grimbeard the Ghastly, the greatest pirate of all times and Hiccup's great-great-grandfather. The coffin contains a living man, named Alvin the Treacherous, who hides his true identity under the name Alvin the Poor-but-Honest-Farmer. Alvin tells the Hooligans that he was locked in the coffin and sent out to sea by "some very rude people". He claims that he found a riddle that tells how to find the treasure of Grimbeard the Ghastly and a map that depicts the island where the treasure is buried.
The Hooligans travel to the Isle of the Skullions, where they believe the treasure is hidden. Snotlout finds a small chest containing Grimbeard's famous sword, the Stormblade. Opening the chest triggers a trap which wakes up the Skullion dragons which inhabit the island. A brief fight with the Skullions ensues, a few of the Skullions are killed, and the Vikings escape with the treasure. Upon nearing Berk, the Hooligans begin fighting over the treasure, and as they fight, they are ambushed by a group of cannibalistic Vikings known as the Outcasts. Alvin reveals himself to be the Outcast's chief, and another battle starts. The ship soon catches fire and sinks. Everyone abandons it, climbing on the Outcasts' ship to continue the battle, but Hiccup, Toothless, Fishlegs, and Alvin are trapped underneath the capsized ship, kept alive with an air pocket.
As the air pocket is finally destroyed by the weight of the capsized ship, Toothless finds an underwater cavern filled with air. As the party begins to explore the cavern they come to a door and upon opening it, they find the real treasure of Grimbeard the Ghastly. Alvin turns on Hiccup to kill him using the Stormblade. In the sword-fight that follows, Alvin is eaten by a Monstrous Strangulator, an octopus-like creature which guards the treasure. As it comes next for Hiccup, Hiccup tricks the creature into injecting itself with its own poison. The creature's nervous system is destroyed and they escape, but Hiccup decides that the world is not ready for the treasure, and leaves it behind.
How to Speak Dragonese (2005)
Hiccup and Fishlegs get lost while out at sea. Toothless is caught by Romans, while Hiccup hides and tries to figure out a way to free him and escape. Hiccup causes a distraction and escapes with Fishlegs, but not before losing half of his How to Speak Dragonese notebook. In the morning, Hiccup realizes he took home a Nanodragon from the Roman Ship. The Nanodragon is, in fact, the king of the Nanodragons and self-proclaimed 'living god', Ziggerastica. For saving his life, Ziggerastica tells Hiccup he can call his name and he will come.
During another lesson, Hiccup and Fishlegs are again kidnapped and taken to Fort Sinister, a base of operations for the Roman Empire. Once there, Hiccup recognizes his old enemy Alvin the Treacherous. Fishlegs and Hiccup are imprisoned along with the young female Bog-Burglar heir, Camicazi. Toothless is eventually allowed to stay with Hiccup. After several failed attempts at escape, Hiccup calls for Ziggerastica and comes up with a plan of escape on Saturn's Day.
When the festival day arrives, the gang are put on a ship and sail into the gladiatorial arena, where they are to fight deadly Sharkworms, rather than a traditional fight on land. However, due to Hiccup's planning with the nanodragon king, Hiccup appears to fly into the air like a God and 'blow' the cage roof off. The stunned Fat Consul gives him his Roman Shield, while Alvin the Treacherous gives Hiccup back his How to Speak Dragonese book. The arena erupts in chaos and the children escape in a Roman Observation Balloon. Alvin manages to get his hand-hook lodged into the balloon basket, but the children are able to twist him off, and he falls into Sharkworm-infested waters. They fly home in the balloon, then crash land onto the ships of Stoick and Big-Boobied Bertha. The two tribes make amends and return to their homes. Unbeknownst to Hiccup, Alvin had planted a Venomous Vorpent within the pages of his book, and it stings someone.
How to Cheat a Dragon's Curse (2006)
During a hunting expedition, Hiccup and Fishlegs spot a group of Hysterics, a tribe of scary lunatic Vikings. Hiccup and Fishlegs flee, with the Hysterics behind in hot pursuit. They are saved by One-Eye, a Saber-Toothed Driver dragon. Fishlegs catches Vorpentitis, a disease caused by the sting of a Venomous Vorpent, and the only cure to this disease requires "the vegetable that no one dares name" (potato) from "the land that does not exist" (America). Old Wrinkly predicts the potato might be in the Hysteric Territories, and tells him that he must bring it back before ten o'clock the next morning, or else Fishlegs will die.
Hiccup brings Camicazi and Toothless on the journey to Hysteria, with One-Eye pulling them on a sleigh. The two children enter through the roof, but Hiccup falls into a pot of onion soup, and is discovered by Norbert the Nutjob. Hiccup makes Norbert show him the potato by pretending not to believe it exists. Norbert locks Hiccup in a cage. After the Hysterics fall asleep, Camicazi picks the lock of Hiccup's cage and they leave the Hall through the chimney.
The three, along with One-eye, escape in Hiccup's boat, but get caught by Norbert and the Hysterics again. They force Hiccup to participate in trial by axe, where Norbert throws his axe in the air and the side that lands in the ground determines if Hiccup will be executed. Hiccup instead catches the axe gold side up, which he says means he should not be killed. At that moment the Doomfang appears, eats the potato, and leaves. Hiccup realizes the Doomfang had Vorpentitis. For saving them from the Doomfang, Norbert lets them go. Once he gets back, he realizes that Fishlegs had only caught a cold, and Old Wrinkly had made a mistake. Old Wrinkly examines Hiccup and explains that it is actually Hiccup who has Vorpentitis. Fishlegs shoots Hiccup in his toe with an arrow soaked in the juices of the potato, and Hiccup recovers.
Hiccup buries the arrow and finds it had a seed on it that has sprouted into a potato plant. He plants more potatoes and no one dies of Vorpentitis ever again.
How to Twist a Dragon's Tale (2007)
While on a herding exercise, the children are distracted by a huge fire rolling down the mountainside. The fire is found to be the doing of evil fire dragons called Exterminators. While most of the kids escape on Gobber's riding dragon, Goliath, Hiccup and Gobber are saved by Humungously Hotshot, one of the greatest heroes on the planet. Hiccup's father, Stoick, hires him as Hiccup's bodyguard.
One night, Hiccup wakes up to Hotshot looming over him with his swords, arguing with himself whether or not to kill Hiccup. Hiccup asks him what he's doing. Hotshot begins to tell Hiccup his story of how he fell in love with a Viking woman, but her father wanted her to marry someone clever. The woman's father sent Hotshot to find and bring back the Firestone, and the reward was the woman's hand in marriage. Hotshot traveled to the volcano where the Firestone was hidden, but was captured by the Lava Louts. After a few weeks, he became friends with a jailkeeper named Terrific Al. Al told Humongous that he would bring the ruby heart to his ladylove if he killed Hiccup, stating that Hiccup is a Devil Child, who will send terror across the Archipelago.
Hiccup figures out that the woman is Hiccup's own mother and "Terrific Al" is really Alvin the Treacherous. Hiccup, his friends, and their dragons travel to Lava-Lout Island to put the fire stone inside the volcano to stop the volcano from exploding. They are attacked by Alvin riding an Exterminator. Hiccup puts the stone into the volcano and the stone hatches into a fire dragon. The dragon eats Alvin and the Exterminators and dives back into the lava.

He throws a tantrum, but remembers that Gobber has stolen the "How to Train Your Dragon" manual from the Library. Stoick tells Hiccup that if Toothless does one more thing like this, he will banish him, and goes off to find the book. Toothless guiltily reveals that he also burned the copy of "How To Train Your Dragon". Camicazi suggests that the library might have another copy of the book.

The noise attracts Driller Dragons who are dwelling in the Library. Hiccup finds a book that was written by Hiccup Horrendous Haddock II called A Hero's Guide To Deadly Dragons which was exactly the same book that had been taken from him earlier that morning.

During the race, Hiccup, Camicazi and Fishlegs are kidnapped and taken to a ship, along with their hunting dragons. On the ship are Madguts, Norbert the Nutjob, and Gumboil. Madguts has agreed to have Norbert take Hiccup, Camicazi and Fishlegs to his boat in order to get them out of the race. Madguts puts Stoick and Bertha in jail and promises he will execute them as his reward for winning the race in three months.
Hiccup discovers there are slaves called the Northern Wanderers on the boat. Hiccup escapes with the Wanderers. After all Wanderers are safe on the emergency boats, Hiccup falls off the boat and lands on an iceberg, and is chased into a cave, where he wakes up on the back of a Leviathorgan. Hiccup gets back onto the boat as a storm breaks out, and the Leviathorgan attacks the ship. Norbert and Hiccup fight on the top of the ship. Lightning strikes Norbert's axe and it enters the sea, killing the Leviathorgan. Hiccup falls off the mast and is rescued by Fishlegs and Camicazi, who are themselves rescued by the Wanderers.

In the middle of the night, the leader of the Uglithugs, UG, and his men, discover the Hooligans, waking them up. UG tells them that a Hooligan has been sending love letters to his daughter, Tantrum O'Ugerly, and explains that if the person is of royal blood, the person can ask for Tantrum's hand in marriage after the person finishes an Impossible Task. If not, the person will be killed. Hiccup realizes that Fishlegs is the one who sent the letters, and spares Fishlegs's life by telling UG that he himself wrote the letters. UG then tells him the Impossible Task: by 5:00 the next day, he must give them a barrel of mead made from the honey made by the bees on the Island of Berserk.
On Berserk, Fishlegs successfully collects five pots of honey, but he and Hiccup are captured by Berserks. At the Berserk Village, Hiccup and Fishlegs meet the other fiancés of Tantrum, one of them being Humongously Hotshot the Hero. All of them are to be fed to "the Beast" later in the evening. Hiccup realizes that the chef of the Berserk Chief is actually his old nemesis Alvin the Treacherous. Hiccup tells Alvin that he can help him escape if he shows him where Camicazi is imprisoned. Alvin agrees; however, while they are in the woods, he pushes Hiccup into a tree cell, where Hiccup meets a witch. The witch gives Hiccup a challenge: she will tell him a story and at the end, they will both guess each other's names. Whoever guesses right will get to kill the other. She tells him the story of Hiccup the Second, who was born a runt as well and was abandoned on a mountainside by his father, Grimbeard the Ghastly. Grimbeard’s wife, Chinhilda, leaves him and sails to the Uglithugs island searching for her lost son, where she eventually became the legend of the crying woman. Hiccup the Second actually survives and is raised by Grimmler dragons with his brother, an adopted Seadragonus Maximus named Furious. Much later, Grimbeard finds Hiccup the Second who has grown to no longer be a runt, and takes him back home with Furious. However, when Hiccup II plans to hold a peaceful protest to protest the enslavement of dragons and humans, Grimbeard is tricked by his other son into thinking that it is violent rebellion and kills Hiccup II, getting his blood on the throne. Furious attempts to jump in front of Hiccup, but is too late. Grimbeard is remorseful immediately after and bids the next king be better than he was. The other two sons sire their own generations, with the one who betrayed Hiccup, Thugheart, banished and forming the Outcast tribe and the other, Chucklehead becoming chief of the Hooligans. The witch guesses Hiccup’s name correctly and Hiccup guesses correctly that she is Alvin the Treacherous’s mother, who is the heir to the Outcast tribe. Hiccup escapes, rescues Camicazi, and they return to the Berserk Village.
Hiccup goes back into his cage just as the feeding of "the Beast" begins. Hiccup realizes that "the Beast" is actually the ancient Furious, who Grimbeard imprisoned underground after killing Hiccup II. Hiccup promises to free Furious if he swears to help him escape and to not harm any humans, with Furious swearing on his heart to agree. Together, they free the thirteen fiancés. However, Furious sets fire to the Berserk woods and reveals he only swore on the half of his heart that loved Hiccup II, and tells Hiccup that a year after he leaves the Archipelago, he shall return to destroy the humans along with a dragon army.
