The New Mexico Territory, 1861. Young Grace, a trans runaway, has headed west, fleeing her Georgia home--and conscription into the Confederate Army. But her coach ride to California makes an unplanned stop when notorious outlaw the Ghost Hawk swoops in, shaking down its passengers and stealing away with Grace. The Ghost Hawk--Flor, to her friends--means to hold Grace for ransom. But when the two get to talking about Flor's plan to crash a Confederate gala, Grace convinces Flor to let her join the heist.
