2015 Reading Challenge [Closed] discussion

This book actually took me a little of guard. First of all, the cover doesn't really accurately depict the novel. This book is about time travel and I don't really get that from the cover.

Otherwise though this book surprised me because I didn't like it at the start! I thought the characters were shallow and the romance kind of fake but by the end of the book my opinion was completely changed. Has anyone else read this? Were you surprised too?
