When tenacious journalist Vivienne Thorne infiltrates a secretive gathering to investigate a string of disappearances, she never expects to be captured by Damien Blackthorn—the enigmatic CEO of Blackthorn Industries who harbors a deadly secret: he's a vampire lord whose powers are mysteriously waning. Instead of killing her, Damien makes Vivienne an impossible offer: marry him in a binding blood contract to help him keep control over his territory, or watch as everyone she loves becomes collateral damage in a brewing vampire civil war. As their reluctant alliance evolves into dangerous attraction, Vivienne learns her mysterious blood disorder is actually proof of a heritage she never knew existed—one that makes her both invaluable and deadly to the vampire world. When her apparently dead father reappears as a vampire hunter determined to destroy Damien, Vivienne must choose between the family ties she's always longed for and the forbidden bond forming with a man she should consider her enemy. But in Shadowveil, nothing is as it seems. As ancient conspiracies surface and enemies emerge from within their closest friends, Damien and Vivienne find themselves pawns in a game centuries in the making. Their blood bond may be their best weapon—or the catalyst that awakens an ancient darkness threatening to consume them both.
