Sam is almost 11 when he discovers a locked box in the attic above his grandfather Mack’s room, and a piece of paper that says he was kidnapped. There are lots of other words, but Sam has always had trouble reading. He’s desperate to find out who he is, and if his beloved Mack is really his grandfather. At night he’s haunted by dreams of a big castle and a terrifying escape on a boat.
