Road to ruin / Hana Lee.

"An electrifying, gritty fantasy from debut author Hana Lee that takes a royal messenger on a high-speed chase across a climate-ravaged wasteland, featuring motorcycles, monsters, and magic. Jin-Lu has the most dangerous job in the wasteland. She's a magebike courier, one of the few who venture outside the domed cities on motorcycles powered by magic. Every day, she braves the wasteland's dangers--deadly storms, roving marauders, and territorial beasts--to deliver her wares. Her most valuable cargo? A prince's love letters addressed to Yi-Nereen, a princess desperate to escape the clutches of her abusive family and soon-to-be husband. Jin, desperately in love with both her and the prince, can't refuse Yi-Nereen's plea for help. The two of them flee across the wastes, pursued by Yi-Nereen's furious father, her scheming betrothed, and a bounty hunter with mysterious powers. A storm to end all storms is brewing and dark secrets about the heritability of magic are coming to light. Jin's heart has led her into peril before, but this time she may not find her way back"--
