Summary:
Meg Daton has been uneasy since the moment she arrived in bayou country. Being volunteer nurse to the shriveled husk of a dying woman she hardly knows is bad enough. But the house, where strange, inexplicable things keep happening, is even worse. And the people! Though Esther seems good-hearted, Wes, her handsome, tight-lipped son, is frightening. Most menacing of all is debonair Dr. LaVane, who treats Aunt Belle behind a locked door. Wes and Doc blame each other for the mysterious death of Wes' sister Anna - a mystery that becomes starkly real to Meg when she begins to realize that Aunt Belle's unexpected "recover" may cost her her life.

I'll take it. It sounds pretty interesting, the setting is a bit off the norm and there's 'bayou' in the title. It's gotta be some level of creepy.
