The Mermaid Chair by Sue Monk Kidd. This 2005 novel followed on the heels of Kidd's The Secret Life of Bees, and while it wasn't as big a hit as Bees, it was well reviewed and many contributors enjoyed it. From Amazon: "Inside the church of a Benedictine monastery on Egret Island, just off the coast of South Carolina, resides a beautiful and mysterious chair ornately carved with mermaids and dedicated to a saint who, legend claims, was a mermaid before her conversion. When Jessie Sullivan is summoned home to the island to cope with her eccentric mother’s seemingly inexplicable behavior, she is living a conventional life with her husband, Hugh, a life “molded to the smallest space possible.” Jessie loves Hugh, but once on the island, she finds herself drawn to Brother Thomas, a monk about to take his final vows. Amid a rich community of unforgettable island women and the exotic beauty of marshlands, tidal creeks, and majestic egrets, Jessie grapples with the tension of desire and the struggle to deny it, with a freedom that feels overwhelmingly right and the immutable force of home and marriage."
