This book was much more than I had expected. I was just looking for something more than the usual vampire/witch/shapeshifter books I've been reading. This series is a race of aliens (yea aliens) that come to protect the earth from another race of aliens. They make this trade agreement with the earth that they can choose mates from the earth's women. The concept of the book sounds like a set up for a bad porn flick. I was kinda expecting some sappy romance but it wasn't at all. Actually there were parts that were so funny I was laughing so hard I cried!
