In a world where everyone has abilities, everyone is the superhero with incredible powers and gifts - the city is divided in how gifted you really are. Kael O'Hara doesn't have the luxury of living in the rich part of town, instead, she resides in the lower-class district. Not only that, but she's apart of a rare gene pool called the Pariah's - the ones without abilities. Due to her defect, everyone treats her like the scum of the earth, the outcast. She spent the majority of her life in the shadows, that is, until a disease targeting people with abilities starts killing people off by the thousands. Everyone is at risk - everything but Kael. She's suddenly thrust into the role of hero, billions relying on her to put an end to the disease, but... after everything they've done to her, why should she save them?
