It made complete sense that Allie Sai, terrified of flying and aliens, would be drafted for colonization of an alien planet. So goes Frost Kay’s latest YA title, Amber Vial. In her mind, Allie feels she has one choice: desertion. But she should’ve known better. A failed escape attempt leaves her chained to an airship chair with nothing but her bag, a vial of her family’s super moonshine, and her anxiety for company.
