Alternative title and cover for B019ATLCWG:

Ellen and her two best friends share a mid-life crisis by hatching a plan to renovate an 1860's Greek revival in the nearby historic district of San Antonio. Although Ellen isn’t one to believe in ghosts, she comes face to face with something inexplicable in the attic. Her ghost-enthusiast friends convince her that they must help the spirit find closure, and as they dig deeper into the past, they uncover a shocking history that someone in the neighborhood doesn’t want exposed. But Ellen and her friends don't give up easily. They realize they've been called to give voice to the invisible women who suffered behind the walls of the house for decades.
