With most of the Viltarans now dead, Natalie Pierce and her small band of friends must find a way to return home. It will be up to them to stop their remaining enemies from turning Earth into a ruined wasteland. Once more, Nat must come to the rescue of the very species that she has begun to loathe. Even worse, she will come face to face with the man who betrayed her and all but destroyed her kind. She might not have control over her own destiny, but Nat will be the one who will decide the fate of her betrayer.
