Blood Tainted Diamonds by K.J. Dahlen

When Barshan takes the deed to a jewelry store in the place of a debt—he finds he’s been ripped off. The real owner, the beautiful Talli Janick, can prove the sale was fraudulent but even more problems await Barshan. He wasn’t the only one who was cheated. When someone representing the Ukrainian mob comes to claim the jewelry store as their own, Barshan stands beside Talli.
Talli’s own stepfather, Russel Jerome sold the jewelry store twice to two separate men, both with ties to different mobs in the city. Then he comes back to steal her inventory. Now everyone is hunting him and Russel takes Talli hostage to get out of trouble.
Can Barshan find her before Russel gets out of town leaving her to pay the price for his crimes?
