I wasn't over impressed with Heart's Sentinel. I read it thinking it would be a light, titillating read and something different from what I had being reading. Sadly it just didn't pass the mustard for me! It was too set on the overall storyline than the actual romance between the main couple. Also the secondary character, the man who attacked and Changed Mac just didn't seem creepy, scary or even insane enough for the story for my personal tastes.
It was more of a sweet, original style romance story with shifters thrown in. I still liked it but would have rated it much higher if there had been more scenes with just Adam and Mac instead of with her father and other members of the pack!
