Since her parents were killed, Vivienne has always felt ungrounded, shuffled through the foster care system. Just when liberation finally seems possible-days before her eighteenth birthday-Vivienne is hospitalized with symptoms no one can explain.
The doctors may be puzzled, but Deacon, her mysterious new friend, claims she has an active Nevergene. His far-fetched diagnosis comes with a warning: she is about to become an involuntary test subject for Humanitarian Organization for Order and Knowledge-or H.O.O.K.
Vivienne can either escape to Neverland's Kensington Academy and learn to fly (Did he really just say fly?) or risk sticking around to become a human lab rat.
But accepting a place among The P.A.N. means Vivienne must abandon her life and foster family to safeguard their secrets and hide in Neverland's shadows ... forever.
