Jake (The Clan Legacy) by J. S. Striker

This is a really good story. It kept my interest from the beginning and even has a few humorous moments. Yes, Jake takes his duties seriously and he is a problem for Gabby. We see a relationship go from frozen to steamy to love. It's not instantaneous, but it grows as Jake tries to protect Gabby, not realizing that he needs to protect Gabby from herself.
