How to Break a Dragon's Heart: How To Train Your Dragon is a literary fiction novel type by Cressida Cowell. The novel opens in the wake of the greatest storm to sweep through the Barbarian Archipelago in more than a century. Camicazi was lost while sailing through the storm and both the Bog-Burgulars and Hairy Hooligans search for her in the dangerous and inhospitable Eastern Archipelago, home to the haunted beaches and both the slavetrading Uglithug and crazy Berserk tribes. Unfortunately, darkness creeps up on them and the Hooligans are forced to find a suitable spot to camp until morning. While searching for said spot, they see a mysterious object on the beach and investigate, Stoick inadvertently causes his boat to run aground and sink and the tribe is forced to camp in Uglithug territory on a beach that is supposedly haunted; the mysterious item turns out to be a spooky ancient throne covered in Hooligan ruins that washed ashore in the storm. As they settle down for the night, Stoick reassures them UG the Uglithug, the merciless slavetrading chief of the Uglithug tribe, rarely visits the beach where they camp because he believes it to be haunted. However, Stoick is wrong and Ug and his men savagely wake the Hooligans in the middle of the night at swordpoint. After making wild accusations Stoick is trying to steal his lands, UG reveals this to be a joke and informs Stoick he actually came to discuss an entirely different and unexpected matter: someone from the Hooligan tribe wrote love letters to UG's daugher, Tantrum O'Ugerly, a crime punishable by death. UG brings out his daughter and reads the letter, telling the Hooligans he will kill all of the unmarried boys and men if the culprit doesn't come forward. Hiccup deduces Fishlegs is responsible for the letters and lies claiming he wrote them to save his best friend; only the son of a chief may write love letters to a chief's daughter or risk certain death. As he endures ridicule and surprise from his fellow tribesmen, UG presents Hiccup with the Impossible Quest to win his daughter's hand, as per viking tradition--collect honey for mead from the bees of Berserk Stoick brings all of his warriors on the quest to increase Hiccup's chances of survival and the boys train immediately. However, during one of the training exercises, Fishlegs sustains a bump to the head and his Berserk traits emerge. Hiccup escorts him home and returns later to discover Fishlegs has gone by himself to Berserk to find his parents and prove he is a hero worthy of a chief's daughter. Hiccup immediately goes to the aid of his friend, knowing the quest is a suicide mission and his friend is unwell. Hiccup stumbles upon a crashed Fishlegs and his chickenpoxer in the forests of Berserk with a bag full of Berserk honey and covered in Scarers, small, blind dragons that rely on fear to find prey, his Berserk mood having worn off. Hiccup attempts to rescue Fishlegs but the chickenpoxer spooks and flies away with Fishlegs still on its back, Hiccup chases his friend and both are ambushed by Poison Darters, dragons in the service of the Berserk chief that shoot tranquilizing darts.
