Lieutenant Grace Lord MD, combat surgeon-in-training, lands her dream job aboard the Conglomerate's Premier Medical Space Station, the Nelson Mandela. The moment she steps onto the station, she is attacked by a gorilla-modified marine turned psychotic by a deadly gas used in warfare. She must survive her assault long enough to save the marine's life. So starts her new job.
Followed by strange androids, attacked by traumatized animal-adapted soldier patients, overworked by a demanding boss with Megalomaniac Hyperactivity Disorder, and pursued by a gorgeous colleague, Grace works hard to be the best surgeon she can be. But when a mysterious ship docks at the Nelson Mandela void of crew, Grace is thrown into a race to discover the cure to the most deadly pathogen the human race has ever seen. Failure means annihilation.
