Seventeen-year-old Diana hasn't left her home in at least a month, but she has the whole online world at her fingertips. Waking up each day at sunset, she logs into the vast world of Garlandía, an online massive multiplayer role-playing game. Offline, she's labeled as autistic and treated like a freak. Online, she's Lune, an up-and-coming video game streamer with a small but steady fanbase. As Lune, Diana can access adventure, admiration, and a future career as a pro-gamer. All she needs is to hit the milestone of one thousand subscribers on StreamLine, and she'll be well on her way.

When Lune crosses paths with the legendary girl gamer Nocht, she may have found the key that will boost her to the upper echelon of streamers. But as Nocht begins to unravel all Lune thought she knew about gaming, friendship, and love, Diana must find the courage to risk building her dreams offline, too.
