This story starts off hitting the ground running and never let's up. The characters are both strong and vividly portrayed. The general plot line was fun. The unbalanced focus on the supporting characters was confusing, especially since the character in the next book wasn't really talked about in this one. I also appreciate the happy ending and lack of cliffhangers.
