I really enjoyed this story. I liked the character development of the characters from the first book. I like how there is an over arching “bad” that we are still following and trying to solve. 
I think my biggest complaint would be that if Maddie is an FBI agent even an intelligence officer she would still be more skilled at combat than she was. 
Other than that I enjoyed the main couple and I enjoyed seeing Jenna and Kipp. I am excited to see Sims story and Zale’s.
