R. A. Nelson takes us on a supernatural thrill ride, a modern-day vampire story set on a NASA base and filled with space-and-science intrigue. Seventeen-year-old Emma feels cursed by her epilepsy—until the lost night. She's shocked to wake up in the hospital one morning, weak from blood loss. When her memories begin to return, she pieces together that it was a man—a monster—who attacked her: a vampire named Wirtz. And it was her very condition that saved her: a grand mal seizure interrupted Wirtz and left Emma with all the amazing powers of a vampire—heightened senses, rapid speed—but no need to drink blood. Is Emma now a half-vampire girl? One thing soon becomes clear: the vampire Wirtz is fierce and merciless, feared even by his own kind, and won't leave a job undone.
