Anne McCaffrey and Elizabeth Ann Scarborough are two of science fiction's favorite authors. Together, they have created the world of Acorna, the unicorn girl. Now, Acorna's children start to have their own adventures. First Warning: Acorna's daughter, Khorii, must contend with an overwhelming legacy to forge a path of her own. A simple journey to visit her relatives turns into a race against time when Khorii comes across a derelict spacecraft drifting in space, its crew dead in their seats. But this gruesome discovery is only a dread harbinger - a deadly plague is spreading across the universe and not even the healing powers of the Linyaari can slow its horrific advance. Khorii, one of the few unaffected by the outbreak, must find a cure before the disease consumes all in its path - including her beloved parents.
