Sam is a teacher in the UK, and Dennis is on death row in the U.S., convicted of the murder of a young girl 20 years previously. His case has always been in the media, as there are many who believe he is innocent. After the end of a relationship, Sam fills her time trawling through all the sites and messages about Dennis and his case, and starts to write to him. Months later she's on a plane to visit him in prison, and before long her life takes a very different turn.
I enjoyed reading this book, though I found Sam's character rather unnerving. She's obviously an educated young lady, but she's also naive, paranoid and jealous - not exactly ideal attributes in life, especially when you start a relationship with a convict. Perhaps it's those that need help themselves, who offer help to others? I wasn't sure whether we should feel sorry for her, or be frightened of her. I think the surroundings she found herself in were such that they changed her completely.
A great book for those who love easy-to-read thrillers. You're never quite sure which way it will go until you actually reach the end.
