The Devil's Heart. Lynn Raye Harris

A diamond, and a deal with the devil… Francesca D’Oro was just eighteen when darkly sexy Marcos Navarre swept her up the aisle – then fled before the ink on the marriage licence had dried. Marcos might have given Francesca a jewel for her finger, but he stole another: the Devil’s Heart – a dazzling yellow diamond he believed belonged to his family…Years later Francesca, no longer so youthfully naïve, is determined to reclaim the precious gem! But she’s forgotten that Marcos lives up to the treasure’s name – and dealing with the devil is always dangerous!
