With eight months to live, Fey Lewis moves to New York City to spend his final days with the surviving victims of the Iris disease. Fifteen children were born with the Iris disease--an extraordinary condition that endows its victim with physical flawlessness and curses them with a 22 year lifespan. The world fell in love with the Iris children. Many of them, like Marcy and Day Darling, became famous right out of the womb. Fey Lewis, however, was sheltered from the limelight, and only in his final months does he decide to experience life the way other Irises do. But crippling anxiety and the overwhelming fear of death stand in his way. The charming, sociopathic Marcy Darling is the Iris' ringleader. Fey can't help but fall in love with her. She renovates an old public school in Alphabet City, NYC and invites the remaining Irises to live under one roof. There is only one rule at P.S. 111: you must record yourself doing something new each day and post it to the Darlings' social media app. As the app and the Irises rise in popularity, Fey realizes Marcy's plans are much more sinister than she lets on.
