In the city of Panacea, a woman's body is not her own — and Evaleigh Oberle has spent twenty-six years making herself invisible to survive that truth, until the morning a government flag appears on her file and invisible is no longer an option. Fleeing into the mountains, she falls into a ravine and wakes in a hidden village, unknown to the Panacean regime, where she discovers she did not arrive by accident — she carries something in her blood that the regime exterminated. But the man hunting her hasn't stopped searching, the secrets her own body is revealing could expose everything, and Evaleigh Oberle — who survived by staying small — is about to leave the first cracks in a four-generation dynasty that has never once faced accountability.
