I loved how sweet and genuine their romance was and how it developed over time without much of the love-at-first-sight concept. The characters were mostly wonderful: Gemma really changed as a person and time-traveler from the start to the end of the book (as did her sister); on the other hand, Harrison was less than perfect - a hopeless romantic all throughout the story. I also really enjoyed the twists and turns Melissa Pearl weaves into her novel. I was constantly interested and didn't feel like she dragged it out for too long. Also, since I usually don't enjoy books that switch POVs, I was a little skeptical after I got to the first switch. But I didn't have to worry for long because the writing smoothed it out and allowed an even better experience for the reader. My main critique would be that it became more and more predictable as I kept reading, and while this didn't lessen my interest in the novel as a whole, I did skim certain parts.
