Although more violent than the first two in the series, the development of the characters is superb. We learn a lot more about Robin's background in this book.
The mystery was wonderfully done and I didn't figure it out although it is fair play. Many will enjoy the references to Blue Oyster Cult rock lyrics.
The narration of the audible book was fantastic.
I couldn't imagine reading this book without having read the first two in the series and would recommend the books be read in order.
