This book was chosen for my Book Club for June. I was really intrigued with the premise of the book, however the reading of it fell short for me. I think the story is there, and it's a really good one, but the telling of it was extremely wordy. I found myself struggling to get through the book because it was just so long without seeming to have a reason to be. I think the story could have been told in about 200 less pages to be honest.

That being said, if you are a person who enjoys reading scientific explanations in your sci-fi books, you probably won't mind the wordiness of this story. Much of the excess, in my opinion, was the attempt to explain how the science of the situation was possible or impossible.

I did enjoy the actual "meat" of the story. The idea of time travel and alternate realities is interesting to me and so that part of the book was what I did love. I also loved the relationship between Tom and Penny and the introduction of Greta.
