Rainbow in the dark

"High school senior Rainbow is trapped with three other teens in a game-like world that may or may not be real. Together, they must complete quests and gain experience in order to access their own forgotten memories, decode what has happened to them, and find a portal home. As Rainbow's memories slowly return, the story of a lonely teen facing senior year as the new kid in a small town emerges. Surreal, absurdist humor balances sensitively handled themes of suicide, depression, and the search for identity in an unpredictable and ultimately hopeful page-turner that's perfect for fans of Shaun David Hutchinson, Adam Silvera, and Libba Bray's Going Bovine"--From the publisher's web site.
