Reva has lived her entire life in secret, hiding in plain sight from a world that would rather see her dead. She has learned how to control her powers enough to escape life unnoticed. But everything changes when knights of a neighboring country arrive at her doorstep searching for her guardian to help care for the Royal Family's youngest prince and his mysterious illness. She sends Reva in her place with an ominous message and her control is tested when she has to live and work under the rule of a kingdom that hasn't employed her kind in hundreds of years. While Reva tries to help the young prince battle this illness, she realizes she didn't leave as much of her life behind as she thought. The Abyss forming in the mountains that separate her country from others has reached beyond her home. Something dark, old, and sinister is brewing, and it's fallen to Reva and her new friends to figure out who and why. Through an unanticipated friendship with a princess and knight of the kingdom she now serves, Reva struggles to find not only her place in this world but who she really is.
