Kelsie Calloway has a little something for everyone. In her earlier days, she wrote sweet beach reads and tender mountain men that made their heroines feel safe and warm.

Now she writes morally grey heroes with a penchant for bad behavior. The women they fall for still feel loved, but it comes with strings attached. Whether they're mafia men, run a motorcycle club, or just can't seem to get a handle on their inclination for murder, these forbidden heroes bring out the darkness in all of us.
