The Twin Stars

Sixteen-year-old Olive Joshi has obsessive-compulsive disorder, and can't stop worrying about hurting the people she loves. She finds refuge in writing about Coseema, a magical princess on a distant planet. Coseema is fearless, confident, and perfect -- everything Olive thinks she'll never be. When she falls through a portal into her own unfinished story, Olive finds herself in a world in peril: double suns scorch the land, the brutal Prince Burnash seeks supreme power, and Coseema is nowhere to be found. Together with her friends -- a bold poet, a cursed musician, a renegade soldier, and an adventurous girl from the desert -- Olive will have to face her deepest fears to find the hero in herself.
