As usual, I loved this audiobook! JR Ward is a masterful storyteller who created this original world existing among the bones of human society. The Viper is the third book in the Black Dagger Brotherhood Prison Camp series and starts immediately after Mayhem and Apex escape the prison camp with Kane who is dying from the severe burns covering his entire body. They get assistance from Rio, Lucan, and his former pack, and Kane is offered a mystical opportunity to be healed and survive if he agrees to host something. (The Viper) He agrees because of his burning need to return to the prison camp to rescue Nadya, the prison’s nurse. While there are numerous subplots in this book, including the Black Dagger Brotherhood searching for the prison, the main story is that of Kane and Nadya. Kane must adjust to his new reality and how it impacts him. Nadya needs to find a purpose and they both have to come to grips with the surprises in store from their pasts. As usual, the story proceeds at an appropriate pace with enough unexpected twists to keep things really interesting. The book ends with a happy ending for Kane and Nadya and plenty of loose ends to keep the series progressing. Even after all these books in this world, the stories are still fresh and fun. Jim Frangione continues to be an excellent narrator and spins the fantastic stories that JR Ward creates. I strongly recommend this audiobook and this series.
