Tender Mercies — Rosellen Brown

Laura and Dan Courser are less than perfect, but deeply passionate couple with young children and lots of plans.  Until Dan, displaying the boyish bravado that made Laura fall in love with him, takes the tiller of a boat he can't handle and causes the accident that shatters their lives.  

Suddenly there are no more ordinary days or nights.  And, in a story filled with astonishing revelations, we witness two people wrestling with a marriage in which all the rules are changed, confronting the guilt and anger, devotion and desire that don't merely survive. . . but can help heal the wounded heart.
