Cassie Sullivan stands in the ruins of a world where trust has died. The alien Others have already unleashed four waves of destruction across Earth, killing billions and stripping away human bonds. Now the fifth wave crashes down, revealing the Others' final plan to wipe out every last human being. Cassie fights alongside Ben and Ringer as they discover how far their enemies will go to achieve total extermination. The survivors haven't witnessed the Others' most brutal tactics yet. But the invaders haven't seen what humans become when pushed to their limits. In this war between species, Cassie and her allies must choose between hope and despair, love and hate, as they face the ultimate question of what makes us human.
