This all-new epic story based on the hit Netflix series Trollhunters—from the limitless imagination of acclaimed filmmaker Guillermo del Toro and DreamWorks Animation—delves into the hidden world of Trolls and uncovers a mystery that has haunted Trollhunters for centuries! For centuries, Changlings have recorded the history of Trolls and Gumm-Gumms in The Book of Ga-Huel. This ancient tome is, literally, a living document with new entries mysteriously appearing—or disappearing—in it. When Trollhunter, Jim Lake, Jr., gains possession of the book, he and his friends are fascinated by what they discover. But when a new passage appears and it points to the death of a beloved friend, the team must race against time to uncover the invisible force predicting a future no one is willing to face.
