I got this book as a gift and was very excited to open up the package. Unfortunately, it's a total disappointment. The author obviously did not do any research on her topic of time travel (which seems so simple in theory and makes it sound like science). She used some words that made no sense, such as:"In fact, my mind is working at warp speed because I'm doing some intense thinking right now.
Bad review

I'm pretty happy with this.
Good Review

This is a book which reads and keeps the reader's attention. It's about how two people who feel an instant attraction discover something wonderful out of their own selfishness. The problem with that is, in real life, we all know some selfishness exists at the same level as most people. One has to take into account how selfish one really is. I also believe everyone wants love regardless where your economic situation is, but it looks like money does not come anywhere near helping out someone in emotional needs.
