Orphan Jack Templar has no memory of his parents and only the smallest details from his Aunt Sophie about how they died. The day before Jack's 14th birthday, things start to change for him. He has only one day before hundreds of monsters will descend on his little town of Sunnyvale and try to kill him. He will have to battle werewolves, vampires, harpies, trolls, zombies, and more. But perhaps the most dangerous thing he must face is the truth about his past.
