I love this series. They are great stories, even if they could longer. The characters are very well developed, if you consider the length of the story. The romance is a little rushed, but once again, I think this has to do with the length.
We met both the hero and heroine in the first book, also written by Carlson (different books in this series are written by different authors). We have Sofia is a master witch. Diesel is a werewolf who cannot control himself during the full moon. His family locks him in a cage during the full moon to ensure that he doesn't hurt anyone.
We also get to see some characters from previous books. Plus, we meet Luke, Diesel's werewolf brother, and Ginger, a succubus and friend of Sofia. They will be the next couple for Carlson's next installment. Not sure when it comes out, but you can bet that I will be buying it.
