My thoughts: Robo, Mattie's smart and well-trained German Shepherd, is still my favorite part of these books. He's so awesome and has so much personality; I love him! I also really enjoy Maggie's and Cole's continuing relationship, as well as Cole's struggle to be a good dad to his two daughters. The two are both such likable characters. And I thought the mystery in this one was interesting and entertaining. But the side story with Maggie and her family felt a little thin, almost like an afterthought. It needed to be more fleshed out in my opinion. This is still a really fun read. I just wanted more of it.
