Blue Moon — Luanne Rice

"At the forefront of this well-crafted story stands Cass, youngest and feistiest of the Keating sisters, a mother of three who en joys hot sex in semipublic locations with husband Billy Medieros, her sweetheart since high school. During a season of emotional and financial upheavals within the Keating clan, the Medieroses' marriage becomes strained in ways that make Billy wonder whether Cass is more devoted to her family than to him. Then Billy adds to the stress by leaving his father-in-law's fleet and buying his own boat. His rebellion sets up the book's unexpected final episode, an electrifying disaster at sea that puts all of the characters back in touch with their deepest loyalties and passions."
