I Want Superpowers — Steven Bereznai

The Genetic Wars that turned most of the planet into a wasteland are over. The so-called "dregs" (short for "DNA regulars") and superpowered "Supergenics" now live separately from each other: the Supergenics in the shiny towers of Jupitar City, the dregs across the river in the squat concrete buildings of the boroughs. But Supergenic children are still born to dreg parents, and under repressive laws must be sent to live with their own kind. To find these special few, every teen faces their Testing Day. When her turn comes, socially isolated Caitlin Feral is determined to Manifest superpowers. If she fails, she faces a lifetime of loneliness and drudgery in the boroughs. But how much is she willing to sacrifice to be the supergirl she's always wanted to be? And when she uncovers dark secrets kept by both sides, does she dare start another war to reveal the truth?
