On October 4, 2016, Graceffa, along with co-author Laura L. Sullivan, released a young adult novel titled Children of Eden, published by Keywords Press. The book follows a Second child named Rowen, who is marked with death due to Eden's population control and recklessly escapes for an adventure after sixteen years of hiding. His book was a New York Times Best Seller on the "Young Adult Hardcover" list in the week of October 23, 2016. The book has received positive reactions from readers on Goodreads and Amazon, with four and five star reviews predominating. Critics have not been universally positive, although Rachel Hyland of Geek Speak Magazine wrote, "Graceffa knows a lot about YA dystopian conventions, and they are all present and accounted for here. This is by no means a bad thing — an enjoyable romp through this genre doesn't necessarily require too much divergence (no pun intended) from the established norms — but it is worth noting that most everything in his Eden has pretty much happened before, in one way or another. Still, it is fun to see just how those ever-trusty elements are put together, and there is a nice twist on the almost essential love triangle that is actually pretty awesome."
