I really liked the family dynamics in this story. They all band together and work together, with the exception of one, and prove a loving and supporting bunch. In relation to the one, I think in a family that has as many people, you are always going to have one member who believes they are more untitled than the rest, but I liked that problems were discussed amongst and solutions found within the members.
I liked Joe and really felt for him, I probably connected with his character more than Mackenzie. They had definite miscommunication problems but once they actually started talking they were resolved without a lot of needless hysterics.
All in all a good read, looking forward to the second one.
