Query: an excellent repeat

I am not a sci-fi or fantasy fan, but this book captured me on my first read, and on the many times I've read it since. It's a human book, that ropes in all of the thoughts and dreams we all have, no matter how they play out. Even if you've never dreamed of going back in time and changing your past, this book will make you think about it, and will make you think about the consequences. It seems like a slightly cheesey sci-fi book on ths surface, but underneath it is a story about the hopes and dreams we all have, and about the time-travel we would all love to try, but secretly fear. I love this book.
