About This Book

What if you were destined to fight a gigantic serpent that could bring the end of the world?

Quick Assessment

Matt, Laurie, and Fen, descendants of the Norse gods, must battle monsters working to bring about the end of the world. When they are separated and each faces a dangerous fight alone, the story explores fear, loyalty, and what it means to stay true to oneself. Expect fantasy battles and sustained peril, with the friendship and self-discovery themes giving the action emotional weight. This is the conclusion of a series, so it works best after reading the earlier books.
