The Time Traveler's Wife - Audrey Niffenegger

The Time Traveler's Wife was an incredibly thick book, yet the story was so compelling that I read it in one day. It moved so smoothly, and the concept and characters were so interesting that I could not put it down. Henry is a Chrono-Displaced Person (CDP), who travels through time involuntarily, usually when very stressed. Clare first meets him when she is six and he is 36. He returns regularly throughout her childhood from different times in their shared future. At last, when Clare is twenty and Henry twenty-eight, they meet in his present, and the relationship begins in earnest. His constant disappearing and reappearing is hard on both of them, yet they are destined to be together and they persevere.
