Thousands of Hollows are turning into Untainted soldiers. The human population is steadily decreasing. Hollows haunt the streets and point them in blood.

Ronan is one of them.

The world is falling apart around Zero Alvarado. Her focus is split into several different directions. Ronan needs saved from himself. The people need saved from the Waters. The Revelance needs an advantage over the Zolarian's.

When a hopeful ally presents itself, Zero seizes the opportunity. Layna, a renowned scientist, has the power to give the Revelance the advantage they so desperately need. The journey to find her sends Zero to territories outside of Earth, where fighting to the death is the only way to gain the mysterious woman's attention.

If there's one thing Zero has learned, it's that friends can disguise themselves under terrifying masks. And so to give humans a real chance of winning the war, she must do what she has always done before: bite or be bitten.
