But they have no future, and not just because she doesn’t know he is a vampire, but because he is not about to stop dealing arms to the Black Dagger Brotherhood. Fate, however, has other plans for them. When Assail falls into a coma and lingers on the verge of death, his cousins seek out Sola and beg her to give him a reason to live. The last thing she wants is a return to her past, but how can she leave him to die?As a lethal new enemy of the vampires shows its face, Sola finds herself not only a target, but a mission-critical force in a war she doesn’t understand. And when Assail’s truth comes out, will she run from the horror . . . or follow her heart into the arms of the male who loves her more than life itself?
