What I love about the entire series- and Flesh and Bone in particular is that although they work as a team, they are not always a completely cohesive unit. They have flaws and carry their doubts affecting how well the team works. They are human- they don't have the super human characteristics of aways getting along. In the real world, under stress- even the best intentions can sometimes cause problems with in a team. In the way, Mayberry keeps his characters real and likable.
The group faces new challenges in the Rot and Ruin. They face new "Bad Guys" like the Church of Darkness and their own inner daemons. The entire storyline keeps you on the edge of your seat. I found myself finishing the book in a couple of days just because I needed to read what happened next.
Although I have to admit, I do not feel that Flesh and Bone is the best in the series ( I still love Dust and Decay and see it as one of the best) the book does not disappoint. Highly recommended 3rd book, it won't disappoint.
