The Child in Time is about a kidnapped little girl. I thought it was going to be extremely difficult to read. I was pleasantly surprised, however, that it wasn't as sad or horrible as I thought. Yes, the main characters are grieving and go through some real difficulties, but there is a message of hope at the end that is very nice. I also liked the intrigue and thoughts about the nature of time that were woven throughout the story.
This is one of Ian McEwan's earlier novels and it is interesting to see how his style developed over the years. This book was not too bad.
