I'm not entirely sure what it was, but there was something about this quick read that I really enjoyed. The beginning was a bit of a hurdle for me because it jumps right into an explicit scene without much set up of the story. Once the story progressed and Cade added some story, plot and world building to the sex, it became highly enjoyable. It had some excellent world building as the story progressed and Stone's character was very dynamic. Rose was a bit naive in the typical damsel fashion, but it wasn't over the top and she did have some strong points. I really enjoyed the frontier aspects of the story, too.
