His Wedding Ring of Revenge

"If you want the emerald back, then marry me." Rachel's words hit Vito like a truck. Rachel's mother was also once Vito's mistress. He would do anything to reclaim the Farneste family's treasured emerald, but he never expected his mistress's daughter, who he once scorned, would grow so beautiful, let alone come to him with such an outrageous deal. However, Rachel, who once fell easily to Vito's temptation, having her innocence stolen and tossed aside, holds a secret as to why she must become Vito's bride, no matter what. Source: Harlequin
