And then there is Dave Boyle, who came home the night Jimmy's daughter died covered with someone else's blood. While Sean Devine attempts to use the law to return peace and order to the neighborhood, Jimmy Marcus finds his need for vengeance pushing him ever closer to a moral abyss from which lie wont be able to return, and Dave's wife, Celeste, sleeps at night with a man she fears may very well be a monster. a monster who fathered her child and hides his true nature from everyone, possibly even himself. A tense and unnerving psychological thriller, Mystic River is also an epic novel of love and loyalty, faith and family, in which people irrevocably marked by the past find themselves on a collision course with the darkest truths of their own hidden selves.
