When his sister, Carrie, is murdered, bookshop owner Myles Foster gains custody of her precocious five-year-old son, Simon. He also has to deal with the reappearance of his ex-lover, Zayne, a private detective. While trying to come to grips with both, another woman is murdered. Myles--with the help of Mazie, Simon's babysitter--learns to adjust to having a child in his life. Having Zayne back in his world is more problematic, since Zayne left Myles for a younger man. Slowly, but surely, Zayne tries to break down the walls between them as they attempt to figure out why Carrie was murdered and pass on their ideas to the detective in charge of the case. Can the murderer be stopped before he kills again? And, more importantly, will Myles be able to cope not only with caring for Simon, but also learning to trust that Zayne might truly love him?
