I read this book on a rainy Sunday morning. I loved it so much that I reread it again that afternoon.
Unfortunately the second time through I became bothered by some problems (as far as I saw it) in the plot. I mean if the guy travelled through time then either he should have ended up in exactly the same place but at a different time (so no spacial displacement) or you could argue that if he travelled in time and the earth moved then he should end up somewhere different but predictable.
But it just seemed to be completely random. And that bothered me. It was well written though.
It is a love story about a man with a genetic disorder that causes him to time travel unpredictably, and about his wife, an artist, who has to cope with his frequent absences and dangerous experiences.
Its a very good novel written by an american author.
