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.
