Book two in the Muses series brings us Navy Seal, Hunter, and the psychologist, Callie. He is sent to her after a rough mission, but he has no interest in talking and getting his head examined by an "old man". When he discovers that his doctor is a beautiful female he still doesn’t want to talk about how his mission went wrong but he does want to go out on a date. Callie holds out strongly and stubbornly, but Hunter draws her in and when she discovers he is her Guardian it makes it even harder to resist his charm. As they grow closer, the Kronos Worshipers single Callie out as their next victim and it is up to Hunter to keep her safe. I enjoyed their story. The Order of Kronos is a bit weak for the bad guys. The members are part of a big oil conglomerate and yet they have to brain wash someone in order to make him fanatical enough to murder without question. They need to be more ruthless and aggressive. They come off as a bit passive compared to the strong protagonists in the story. Other than that, I enjoyed book two as much as book one. Looking forward to reading about Reed next.
