Kacen Callender, National Book Award winner of King and the Dragonflies, delivers a stunning novel that invites readers into a child's struggles with mental health, and their journey to wholeness.

Moon's depression is overwhelming. Therapy doesn't help, and Moon is afraid that their mom hates them because they're sad. Moon's only escape is traveling to the spirit realms every night, where they hope they'll never return to the world of the living again. The spirit realm is where they have their one and only friend, Wolf, and where they're excited to experience an infinite number of adventures. But when the realm is threatened, it's up to Moon to save the spirit world. With the help of celestial beings and guard­ians, Moon battles monsters and shadows, and through their journey, they begin to learn that a magical adventure of love and acceptance awaits them in the world of the living, too. This story of hope shows readers that our souls blossom when we realize that we are as worthy and powerful as the universe itself.
