LEGEND OF TREY VALENTINE by Teri Santitoro

Trey Valentine, a proficient gambler, finds himself embroiled with a mysterious woman from the local brothel. Despite not being able to remember his nights with her, he is drawn back over and over.
 
When a young woman named Sarah enlists the gambler's help in finding her sickly and missing brother, they are both caught up in the mystery of the brothel and its women.
 
An old Gypsy woman may have the answers they both seek but her intentions are not clear. Danger hides behind every corner and lurks in the shadows, hunting Sarah and luring Trey back to the arms of the women in the brothel.
