This book rocks! I recommend this book to everybody I meet who indicates the slightest interest in reading. Without giving away any of the important stuff - it is NOT a sci-fi story at all, but essentially a story about everyday life as we know it, where a man and a woman come together in the most amazing way. Time travelling in this context is a strange thing that happens to Henry, which is bizzarre in context, yet such an acceptable idea in the story. It will make you laugh and cry and you have great difficulty putting it down. When I had completed the read, I didn't start another book for about 5 days, so as not to spoil the wonderful feeling which remained.
