His Blood — Christine Morgan

Vampires. Vicious, hungry, soulless monsters. With an aversion to crosses… but not for the reasons traditional lore would have us believe. The truth has been twisted, hidden, buried by over two thousand years of misinformation, conspiracy, and spin. Now a brilliant scientist who's also a religious fanatic is determined to bring about humanity's salvation by whatever means necessary -- with an innocent young woman at the heart of his plans -- and no idea of the horrors he's about to unleash. An ancient secret society faces a renewal of their age-old battle against the undead… with the sole survivor of a massacre as the only witness to the theft of an artifact that could mean the end of everything they've fought for. Behold the power, and peril, of HIS BLOOD.
