No good deed goes unpunished. That's what they always say, isn't it? Haitian relief coordinator Dr. Mason Walker didn't expect to begin his day staring down the barrel of an AK-47 wielded by a twelve-year-old child soldier. He also didn't expect to end it with the revelation that the darkly beautiful, otherworldly woman he's just met is truly otherworldly, in the most literal sense of the word. She claims to be a vampire. But Mason is a doctor. A man of science. And everyone knows that vampires are just a superstitious response to the medical condition porphyria, combined with ignorance about the behavior of corpses after burial. Besides, he has bigger things to worry about right now. Haiti's war orphans are going missing. And when they return, they are... changed. Mason suspects rebel military commanders of brainwashing them with a new cocktail of drugs, turning innocent children into mindless killing machines. When his delusional but strangely alluring muse and her eccentric friends decide to get to the bottom of the mystery, Mason is tipped headfirst into a world that will make him question the very foundations of his reality. And if they're not very, very careful, someone's going to end up dead before the night is over. * * * The Circle of Blood Series In another lifetime, six vampires lost their mates-and their mortality-to an unimaginable evil power.
