The family’s choice changes everything: bionic Ava stays, and Lily is sent away to Compliance Station Seven as Unit 526. She returns emotionless, controlled by commands she can’t resist, while Ava uses that weakness to her advantage. A terrible birthday disaster pushes the deception into the open. Shaken by guilt, her family works to repair the damage, and Lily later dedicates herself to rescuing other teens trapped under the same conditioning.
