Dragonvine

Dragonvine is the upcoming second post-How to Train Your Dragon 2 graphic novel. It will continue the story of The Serpent's Heir. The publication date is subject to change, but as of now, both electronic and paperback versions are set for September 4, 2018.

Overview
This second standalone graphic novel based on the film series is a new adventure that takes place shortly after the events in How to Train Your Dragon 2 during the period in which Hiccup is desperately trying to fill his father’s role as the chief of Berk. Created with the help of the film’s writer, director, and producer, Dean DeBlois, it bridges the gap between the second and third films.

Synopsis
"Hiccup, Toothless, and the rest of the dragon riders encounter two deadly yet mysteriously linked threats: One is an island consumed by Dragonvine, an uncontrollable force of nature that’s poisonous to humans and deadly to dragons. The other is an all-new, all-terrifying dragon species–the web-spitting Silkspanners!"

"''Trapped by the Silkspanners, a mysterious new species of web-spitting dragons, Hiccup and Toothless must lead their friends in a fight for freedom. But escaping the Silkspanners is just the beginning. When our heroes encounter a group of villagers in peril from the deadly Dragonvine plants, they must put themselves at risk to help their new friends.

''But are the villagers friends? Or is the Dragonvine part of an evil plan? And how do the Silkspanners fit into everything?"'' -Back cover
