Oh my goodness, this book was so hard to put down! I have listened to many of the books in this series but this one by far was more intense and, yes, was a true nail-biter. In book 10, John and Julia are newly married and expecting when he finds out that he has a 10 year old half brother that is with a scary and very dangerous couple of bank robbers. John now must rescue him before he is caught and sentenced to hang with the men he knows is controlling the boy. John finds himself back in the Rookery and other filthy and dodgy places of his past. Most of these books have been really clean and closer to the PG side of the ratings, however with the people and areas John is thrown into this book really pushed it into the PG13 side. The language is still pretty clean but there is more violence and sexual content, no actual scenes but illusions are stronger (ex. in one part he is in a brothel and the thin walls allow him to hear and picture exactly what is taking place in the other room). As a parent I would be fine with high school and up for this one. The narrator is absolutely perfect and truly makes this an incredible audio book!
