Wench : a novel / Dolen Perkins-Valdez.

Tawawa House in many respects is like any other American resort before the Civil War. Situated in Ohio, this idyllic retreat is particularly nice in the summer when the Southern humidity is too much to bear. The main building, with its luxurious finishes, is loftier than the white cottages that flank it, but then again, the smaller structures are better positioned to catch any breeze that may come off the pond. And they provide more privacy, which best suits the needs of the Southern white men who vacation there every summer with their black, enslaved mistresses. It's their open secret. Lizzie, Reenie, and Sweet are regulars at Tawawa House. They have become friends over the years as they reunite and share developments in their own lives and on their respective plantations. They don't bother too much with questions of freedom, though the resort is situated in free territory--but when truth-telling Mawu comes to the resort and starts talking of running away, things change.--From publisher description.
