<b>From the back cover of the Roc first edition:</b> "The human experiment - Twila Grimm was a pure survivor, raised within the sterile limits of the Biodome. But stretching for miles beyond its transparent walls were the great and terrible mysteries of the Outside. It was where the infected were free to roam... it was where souls poisoned by the devastating CM virus waited to die... and it was where the secret of Twila's true origin was buried. For even among the survivors, Twila is different.
<p>Dr. Krell, Chief of Immunology Research, knows this. In the name of science he has use Twila in his experiments. In the name of freedom Twila must escape.
<p>But an even greater danger awaits her in the Outside: the warring factions of civilization that have turned the once beautiful mesas into a slaughterground... the Flyers, who tread a fine line between sanity and madness... and the astonishing truth about her own natural destiny that could prove the ultimate destruction of both worlds..."
