The Haunting of Sarah — Anne Logan

Louisiana: the enigmatic bayou, the moss-draped river trees, the ghostly city of New Orleans, a setting for devilish intrigue and dangerous love. Four talented authors who make their homes in this mysterious state conjure tales of three desperate women and a man who, long ago, dared to dance with the devil, risking souls for hearts' desire...and finding love.

When her childhood sweetheart rejected her, lovely Sarah married his twin to provide for her family. Now, trapped in a cruel marriage, she offers her soul for one night in the arms of the man she should have wed.
