No one is more surprised than Rennie to hear that his late grandfather, whom he hardly knew, has left a mission for him to fulfill. Rennie is to fly to Iceland and deliver a message from beyond the grave, but when he gets there, nothing is simple or straightforward. For one thing, Brynja, the teenage daughter of the family he's staying with, is downright hostile. Her father Einar, who is to be Rennie's guide in Iceland, is preoccupied with looking after his elderly father-in-law, an old friend of Rennie's grandfather. Bored and a little bit annoyed, Rennie explores the town and becomes aware that the family is dealing with more than their grief over Brynja's mother's death the year before. Before he realizes what is happening, his curiosity puts Rennie in grave danger, with no one to trust and no one to save him except himself.
