your name. (light novel) by Makoto Shinkai

Mitsuha, a high school girl living in a small town in the mountains, has a dream that she’s a boy living in Tokyo. Taki, a high school boy in Tokyo, dreams he’s a girl living in a quaint little mountain town. Sharing bodies, relationships, and lives, the two become inextricably interwoven–but are any connections truly inseverable in the grand tapestry of fate?
Written by director MAKOTO SHINKAI during the production of the film by the same title, your name. is in turns funny, heartwarming, and heart-wrenching as it follows the struggles of two young people determined to hold on to one another.
