How we became wicked
(Book)

"A Caitlyn Dlouhy book."

"A viral disease called 'the wickedness' plagues the world, and sixteen-year-olds Astrid and Natalie are two of the only people immune. The girls live in separate, isolated communities, but recent encounters with wicked people link their stories in unexpected ways"--,Provided by publisher.

A plague is pulsing through the world. Already infected by the droves of Singers, the ultraviolet mosquito-like insects who carry the plague, the Wicked roam the world freely. They don't want much-- only to maim and dismember you. And they always ask politely first. The True live in contained, isolated communities. They found safety from the Singers, and the threat of the Wicked has been contained. The Vexed survived the sting of the Singers, leaving them immune... but far from safe. The Vexed hold the key to a cure, and there are those who will do anything to get it. -- adapted from jacket
