The fate of humanity comes down to one last fight....

The odds are stacked against Lyla Richards as the final battle looms. The Naku underestimated her before, they won't do that again. They will throw everything in their power at her to keep her from retrieving Miles.

But they don't understand human emotions. They don't understand a mother's love and how far she will go to get her son back.

And as one last secret is exposed, Lyla will have to choose humanity's fate. Because her decision can lead humanity to their ultimate success...or their complete domination.
