Enter Grace, a thirty-ish young woman who hasn't the self-assurance to say "no". Thus, when faced with the escalating sexual demands of male friends, she doesn't know how to ratchet down the intensity. Rather than hurt their feelings with rejection, she kills them. Nothing personal, you understand, she only wants to be decent about it.
Enter Sam, a former KGB crack assassin. Now that the Cold war is over, he lives in the U.S. working as a contract killer. He encounters Grace while randomly testing a wireless eavesdropping system, and something in her demeanor prompts him to begin following her around. He becomes witness to her killings, and is fascinated by her modus operandi and what he speculates to be her motives and state of mind. He is smitten.
The book's 55 chapters - they're short - alternate back and forth between the Grace and Sam viewpoints. As the two eventually meet and establish a relationship, each acts as a therapist for the other. Grace acquires self-assurance and fortitude. Sam becomes a more compassionate hit man.
This novel by Jen Sacks is quirky enough to be worth buying. Some readers may also perceive in it nuggets of insight regarding the dating/mating ritual between the sexes. The ending is neither profound nor unexpected. It's, well ...NICE.
