EndWalkers

For Verity Monroe, the world ended five years ago with acid rains and fire twisters. And now she's helping to keep it down against her will, until the last bit of humanity is snuffed out. Except a tip-off from a mysterious figure leads her to a laptop. A Console, in reality, which revealed that the world they lived in was simply a level in a Game. A Game that if they won, would stop every apocalypse in the entire System. Accompanied by Asadullah Khan, a catshifter from a robot-ridden Level, she and her friends are thrust into worlds of zombies and plagues. They work through the Levels, meet allies, get stronger, all with one goal: Get through the End.
