Robert B. Parker's Blood feud
(Book)

Sunny Randall is "on" again with Richie, the ex-husband she never stopped loving and never seemed to be able to let go, despite her discomfort with his Mafia connections. When Richie is shot and nearly killed, Sunny is dragged into the thick of his family's business as she searches for answers and tries to stave off a mob war. But as the bullets start flying in Boston's mean streets, Sunny finds herself targeted by the deranged mastermind of the plot against the Burke family, whose motive may be far more personal than she could have anticipated
