Instead, she wakes in a facility built to dissect the Variant gene. Her power isn’t being removed—it’s being mapped, copied, and stored. Ethan Vale, her estranged brother, has spent years suppressing his own gift. But when Lena disappears, he’s forced to confront the truth about Horizon—and the past he’s tried to forget. As their powers resurface, and their connection deepens, they uncover a terrifying plan.
