Query: Back to the Future

This was a great book I could not put it down. It made me think of what it would be like to go back to the Old West from the 21st Century.Trey and Amanda's reactions to their different worlds keeps the story moving right along.I like to read historical romances and this is one of the best.It makes me want to look for a white horse to show up in my yard. I would highly recommend this book it is a good light summer read,one that helps you to escape from the real world for a while. I give this book 5 stars.
