Numbers rule medical examiner Dr. Mei Sharpe's life. At fifty-five years old, she has no husband, one friend, two daughters, and three chance encounters 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 the recent widow directly in the path of Lieutenant Morgan Kelly-the affable, thirty-five-year-old detective from the Sheriff's Department. More golden retriever than hard-boiled detective, Morgan is a talented investigator with a knack for opening people up. A ray of sunshine who determinedly hides her dark clouds. She slowly melts the frosty scientist, and an unexpected romance heats up between them. Morgan is patient, but her traumatic past makes her unsure if she'll ever be enough to win Mei's heart. Mei wonders if it's even possible for her heart to love again. In a battle between grief and guilt, and desire and doubt, Mei and Morgan find they're no match for the universe and its nudges toward what the heart really wants.
