Query: Best of the MacAllisters so far....

Out of all the MacAllister novels so far, I enjoyed this one the most. Sin was one of my favorite characters from "Claiming the Highlander" (the story of his younger brother Braden, and the first book in the MacAllister series.) When you have a character you really like, and you are waiting for their story, often times you are let down, because the actual story doesn't live up to what you've built up in your mind. Sins' story however lived up to my expectations. He was very human, especially for a 'hero', and our heroine Callie is great. She's far from a shrinking violet, and Sin needs a strong woman to help him conquer his ghosts. The MacAllister series in general is a great series to get lost in, but "Born in Sin" is my favorite, and I strongly recommend it.
