BLOODS AND CRYPTS   Once again, America is under siege. A devastating terrorist attack has destroyed one of the nation's most treasured landmarks. With Mt. Rushmore now reduced to a pile of rubble, Major Josiah Key, commander of the secretive Cerberus Unit, is dispatched to hunt down the mastermind responsible: the most fanatically evil extremist the world has ever known. And he's hidden in the most isolated region of the Hindu Kush mountains of Afghanistan.   Climbing to the fiend's remote, mysterious caves, the four-person Cerberus team encounters bloodless corpses that lead them to confront one of the greatest evils in human history: the Vetela...unholy creatures who inhabit the bodies of the dead and the source of all vampire legends. Their sole purpose is to guard the terrorist, and with his help, the Vetela, are finally ready to come into the light and lay waste to all humanity.
