The 19th book in Sherrilyn Kenyon's Dark Hunter series, No Mercy is a combination of love story and sci-fi adventure. Dev Peltier is a Were Shapeshifter and for centuries has been protecting Sanctuary, the New Orleans haven for Immortals. Samia Savage, a former Amazon queen, is a Dark Hunter, a servant of Artemis whose goal is to destroy Daemons and keep humanity safe. Although Sam is normally immortal, a new powerful danger has appeared and Dev is given the task of protecting Sam. Even though love between a Were and a Dark Hunter is forbidden, the close contact results in some very hot romance.I enjoyed the Greek mythology and history intertwined in this story. Many famous gods make appearances in this story as their petty rivalries and interference in the mortal world was entertaining. It almost seemed like a Percy Jackson story for adults. What I did not enjoy was the sappy romance. The characters seemed stereotyped and one dimensional. But if you are in the mood for action and steamy romance with a paranormal cast, then this might be a good choice.
