I really enjoyed this book. I think I enjoyed the first 75% the most though and thought it kind of lost steam toward the end when all of the crazy drama was coming out. There were several times that I found myself laughing hysterically while reading Mack Daddy. There were some really funny scenes. I liked that we got brief glimpses of Mack and Frankie's past and it was cool how Mack tied their memories in with stories relative to his son's current life. 
 There were a few things that didn't add up quite right and stuck out to me, but nothing that really brought me out of the story. A couple examples would be: The fact that the third roommate was talked about at the beginning of the story, indicating that he is still involved in both Frankie and Mack's lives, but then we never heard from him or about him again in their current lives. He was mentioned during the flashbacks to the past of course. That didn't really make sense to me. Where was this guy they both speak with and keep updated on life happenings? Also, a scene where Mack takes off his "wet" shirt while he is at home. He lived at least 30 minutes from the school and was dunked in water a while before he even left the school. How was his shirt even damp by the time he got home? Trivial, I know, but little things like that stick out to me. 
 Overall, I give Mack Daddy 4 stars. I would definitely recommend it. 
 Audible: I added the whispersync Audible narration to this Kindle book. There were two narrators as the book was told in alternating POV with both our main characters. The narration was really easy to listen to and both readers did a great job.
