The Twin Stars by Bridgette Dutta Portman

Olive Joshi is an imaginative and anxious sixteen-year-old. She finds refuge in writing stories about Coseema, a magical princess on the distant planet Lyria. Coseema is fearless, confident, powerful, and perfect — everything Olive thinks she’ll never be. When she falls through a portal into her own abandoned story, Olive finds herself in a world in peril: double suns scorch the planet, the brutal Prince Burnash seeks supreme power, and Coseema has gone into hiding. With the fate of a star system on the line, can Olive find the hero in herself?
