The K'laadians have watched Earth for over five centuries, and it is finally ripe. A rich planet with all they need–water, breathable air, fertile soil... comfortable. But most important–sufficient technological infrastructure and labor, because someone has to perform the work. When K’laadia targets Earth as its next acquisition, Dr. Maggie Kestler and the Sally’s Pride crew are plucked off the ocean to become pawns in negotiating a surrender. Why attack and destroy valuable infrastructure if you don't have to? Never defeated, K'laadia knows success is assured. Fighting a battle of wits with their captors, Maggie and her crew desperately want to warn humanity, only to discover an even greater danger. Their final solution will challenge all their hopes and beliefs... because the K’laadians just may not be the greatest threat to humanity.
