When Derek Brighton gets called in to provide assistance on a case involving a serial killer, it gives him the opportunity to sign a contract with Karina - especially since she thinks he can't stand her. Karina is a strong willed private investigator who is used to handling cases on her own and doesn't want to take orders from Derek. That is, until he uses his Dom voice on her. But he needs to make sure she will do as he says as they pose as a couple to try and find the killer.
Even with the best laid plans, Karina does get in a dangerous situation but she has trust that Derek will search for her. There were some new characters that we meet and I loved how Karina handled Maia.
