Rebel of the Sands By Alwyn Hamilton

Amani Al’Hiza is all three. She’s a gifted gunslinger with perfect aim, but she can’t shoot her way out of Dustwalk, the back-country town where she’s destined to wind up wed or dead. Then she meets Jin, a rakish foreigner, in a shooting contest, and sees him as the perfect escape route. But though she’s spent years dreaming of leaving Dustwalk, she never imagined she’d gallop away on mythical horse—or that it would take a foreign fugitive to show her the heart of the desert she thought she knew.
