Think of something that you would die for, then live for it. That's the advice Luis, a world-wise Cuban exile gives Caro Venable, who has been living in a soul-shredding haze of sorrow since the death of her young daughter. Caro, the appealing heroine of Anne Rivers Siddons's Low Country, read here by Debra Monk, takes that advice to heart when she faces the loss of the island she treasures to a development company one, unfortunately, controlled by her own husband. Siddons, a natural storyteller, is at her best here, conjuring up the mists and marshes and shaggy wild ponies of the South Carolina low country, creating characters with enough substance to stay with you long after the cassettes stop spinning.
