The boy on the gurney is dying. Held at gunpoint by a subterranean terrorist, Dr. Rayne Garcia fights to save his life. One false move will put everyone in danger. She's seriously regretting volunteering at the third-floor free clinic when she usually works in one of the Eastern Coastal City skyscrapers.

Kaelyn Dark doesn't like the label terrorist when all she wanted was to protect her people against the military units sent by the corrupt Celestial authorities. Kaelyn has brought the child, critically injured during a Celestial raid, into an enemy clinic. Attempting to save his life is reckless and desperate, but she's unable to foresee how intertwined her and Rayne's fates will become.

Meeting Kaelyn fuels Rayne's suspicions about the propaganda fed to her and other Celestials. Once she takes a stand for what is right, she can never return to her opulent way of life--but can she survive the harsh conditions? A daring plan to migrate the subterranean population to live above ground--in peace, is underway. Kaelyn's fought her entire life for this, and she can't allow herself to fall for Rayne. If she loses focus and something goes wrong, it could mean the end for all of them.
