Cassandra de Warenne spends her days in an English manor, looking after her young niece while her sister Tracey lives the life of a jet-setter. When Cass meets Tracey's newest conquest, Antonio de la Barca, she isn't prepared for the intense and immediate attraction -- an attraction that heralds something deeper, more powerful, and more dangerous than Cass could ever imagine.
For the de Warennes and the de la Barcas have a tangled history of heartbreak, rivalry, and bloodshed that began 450 years ago, with Isabel, forsaken and betrayed by her family, lover, and friends. Today, Isabel has summoned the two families together one final time -- this time to complete a quest for vengeance from beyond the grave.
