Once again, the story is told by A, who wakes up every day in a different body. Now A knows that they are not the only person who does this because A and Nathan are being pursued by Poole, who can stay in a host body for more than 24 hours. However, they are not the only ones. How many are there? How many lives do they touch? Is one body, one life, one person better than any other? I enjoyed this intriguing book.
