When Joey Graceffa released his debut memoir In Real Life last May, it promptly soared to the top of the Amazon Humor charts. And now, with his follow-up literary effort, a dystopian young adult novel titled Children Of Eden, it looks like Graceffa has another hit on his hands.

After launching on Oct. 4, Children Of Eden debuted at the top of the most recent New York Times Best Seller list within the Young Adult Hardcover category, according to the Times. Children Of Eden, which Graceffa announced on his YouTube channel in July, follows heroine Rowan — a twin born in a future society where families are only allowed to have one child apiece. After being hidden away in her family’s compound for years, she escapes for one night of adventure, which sets into motion a world-changing chain of events.

Graceffa tweeted yesterday in response to the news:

Children Of Eden is being published by the same team behind In Real Life — Keywords Press, an imprint of Simon & Schuster founded in partnership with talent agency UTA that has also released books by YouTube stars iJustine, Shane Dawson, Shay Carl, and Connor Franta. The book is available in the U.S., U.K., Canada, Australia, and New Zealand.

Graceffa, who won a Streamy Award for ‘Ensemble Cast’ last week for his YouTube Red series Escape The Night, is currently on an eight-city book tour in support of Eden, which kicked off Oct. 5 in Los Angeles and will conclude this Sunday in Orlando, Fl. Check out a short film created by Graceffa based on the first chapter of the novel below, or order a copy of Children Of Eden right here.
