Numbers rule medical examiner Dr. Mei Sharpe's life. She has no husband, one friend, two daughters, and three random meetings with the same woman within four weeks. Upon the third meeting, even Mei in her empirical rigidness must admit the universe is nudging her. A nudge that lands her directly in the path of Lieutenant Morgan Kelly-an affable detective from the Sheriff's Department. More golden retriever than hard-boiled detective, Morgan determinedly pulls the asocial widow out of her shell. As the frosty scientist warms up, and an irrepressible chemistry develops. Morgan is patient, but questions if she'll ever be enough to win Mei's heart.

Mei questions if it's even possible for her fall in love again at all. However, through grief and guilt, desire and doubt, both women find they're no match for the universe and its nudges toward the revelations of what the heart really wants.
