Kyle encounters death when a train is derailed as he is travelling on a school trip. The only way to avoid death is to live in the nightmares of the other passengers.
Malorie Blackman admits that she has based the nightmares on some that she has had and that she has used some of these in other stories she has written. A full list is provided on the copyright page. She also admits that she has been able to pinpoint the real life events that have led to the nightmares. This is all discussed in the Author’s Note at the end of the book. Possibly the book could lead to a discussion on the interpretation of dreams.
There is plenty of tension and pace throughout the novel and Blackman keeps us guessing as to whether Kyle will survive and if others in the train crash will live.
