Charlie O’Reilly is an only child. Which is why it makes everyone uncomfortable when he talks about his brother, Liam. His kid brother, who, up until a year ago, slept in the bunk above, took pride in being as annoying and could make Charlie laugh until it hurt. Then came the morning when the bunk, and Liam, disappeared forever. Then Charlie receives a mysterious note from Liam, leading Charlie and his best friend Ana to make some profound discoveries about a magic they didn’t know existed, and they soon realize that if they're going to save Liam, they may need to risk being forgotten themselves, forever.
