A chance meeting on the Isle of Palms brings former sweethearts Adam Stanley and Eve Landers together again. Their respective spouses, Eliza and Carl, fight sparks of jealousy flaring from their imagined rekindling of old flames. As Adam and Eve get caught up on their lives, their partners strike up a deep friendship of their own. Year after year, Adam, Eliza, Eve and Carl eagerly await their reunion at Wild Dunes, a condominium complex at the island’s tip end, where they grow closer with each passing day. The devotion and love they share will help them weather the vagaries of time and enrich their lives as circumstances change, their children grow up and leave home, and their twilight years approach.
