Looking Glass Lives by Felice Picano

Stories within stories, secrets buried for generations, and the ghostly presence of a tragic figure from Civil War times haunts a seaside Rhode Island town and the lives of sexually precocious cousins Roger and Chas Lynch. When grown up Roger returns to live in the town's "haunted house" with his new wife, he discovers its cruel story. And the cousins' love triangle plays out eternal cycles of passion, jealousy, and perhaps also redemption.
