Query: Unbelievable!

My suspicions were confirmed that Sandra Brown has written romance novels in the past. That was my assumption when I read this book. The characters were shallow, the surprise ending was predicted, and nothing about this book was believable. It was fast-paced, and I finished it, but it is one of the least favorite books I've read in a while. We selected this book at my book club, and nobody seemed to enjoy it very much. Overall, it was just ridiculous!
