Spiritual forces are at work to destroy mankind...Dr Ellen Larson has heard myths of fallen angels, but she has no idea they exist-or that they're after her. She has enough on her mind--her research and her own strange DNA, which she's kept secret since she discovered a mutation in medical school that's never been seen before. Then the impossible happens. Two patients admitted to the University Medical Center-Rafe Zacharias and Homer Wilton--have the same genetic mutation! Without transfusions, the men will die. Ellen can't withhold what may be their only hope: her blood. She has no choice... Her secret must come out. Unseen, a battle rages around them. A battle to bring an ancient curse to life. Ellen, Rafe and Homer are pawns in a war mankind can't afford to lose...
