Genetic scientist Soren escaped Helix Corporation's secret lab with three "children"—but these weren't ordinary kids. Seven-year-old Knox could hear everyone's thoughts within 50 meters (and couldn't turn it off); five-year-old Lumi surged with strength enough to lift cars whenever she was happy or angry (she thought everyone could rip doors off their hinges); two-year-old Ozzy randomly teleported to any spot within 500 meters whenever he cried. Soren had already cycled through 27 nannies—all broke and fled within 48 hours. The 28th nanny arrived: Vex. Smiling gentle, great cook, perfect resume. But Vex wasn't there for the job—she was a top Helix agent sent to recover the "subjects." Her mission: infiltrate, collect DNA samples, wait for extraction team. But when Lumi first lost control and lifted her overhead into the pool, when Knox quietly walked up to her and said "I know what your heart is thinking—you're thinking how to take us away, but your heart is thinking something else too, you want to stay," when Ozzy teleported next to her pillow at midnight and patted her face with a tiny hand saying "Ma"—Vex's mission and her heart began a war she was destined to lose.
