Joel Wilde, an ex-Marine turned security specialist, is asked by one of his Marine buddies to guard his sister Lora because he is afraid that people he owes money to are going to hurt her. Joel agrees to keep his mission secret, and with a history of uncommitted relationships, decides in advance to keep things with Lora strictly professional. But after some men attack her, Joel is forced to tell her the truth, and being alone together in a remote cabin does not exactly lead to "strictly professional" behavior. The sex is hot and frequent, with no love declarations made, even though they are increasingly felt. A secondary story line involves Lora's friend, a single mother who falls for her daughter's math teacher. Denison sensitively pairs men with commitment phobias and women willing to wait, creating a good read with sensual sex scenes. Happily, a sequel in the works. Chelton, Mary K.
