Bree Claymore was raised on a pegasus, soaring across the sky and working the pegasus ranch her family built from dust and dreams. But when renegades strike, killing her parents and stealing the precious livestock they depend on, Bree and her brothers are left clinging to the remnants of their home.

The mortgage is overdue. The bills are piling sky high. And the ranch, the only piece of their parents they have left, is slipping through their fingers.

Determined do something, Bree sneaks past her protective brothers and talks her way into taking the winged courier test, for a dangerous, but incredibly lucrative job that offers a shot at saving her home. To everyone's surprise she passes.

Bree begins winging her way from outpost to outpost, dodging renegade bullets and pushing herself to exhaustion. But danger rides the wind, secrets lurk within the clouds, and the renegades that destroyed her home aren't done with her or her ranch. Bree will have to risk it all- her freedom, even her life- to save her family and home.
