I think this was a solid 4.5 for me. So I keep waffling between 4 and 5 stars for rounding... I'm settling on 4 though because if there is a question I feel I should round down. 

The plot itself felt a little dry and long for me. The actual material, not the book itself. The characters were very intriguing as people and how the story was told was very engaging. I just felt the plot itself ran on a bit long and could have used a little something more. A little more what? I don't know. But it just didn't quite hit that 5-star "wow" factor for me. 

It was a fun read, a compelling read, a book with something to say and it said it quite well. Maybe if someone liked real life and literary fiction a bit more than I do this would be a solid 5. Overall, interesting and a good read for people who want to think about what it means to be human, thinking, intelligent, and forgiving.
