On January 28, 2018, Greg announced on twitter he released the first chapter to his new book to Patreon. He said the book will be complete and available for anyone to read in 4 or 5 months, but his Patreons would "get a head start". He thanked his Patreons for funding his dreams. (Source) On Patreon, he said he will write about events from his life, similarly to his previous two books. He said every chapter will have a version of events from his life. (Source) It does not seem like Greg stuck to this structure as the chapter toward the end of the book contain no stories from his life.
Greg named the main character of Reaper's Creek Daniel, which was Greg's last name before marrying Kai. This is similar to his first book where he named the main character after his middle name, James.
After the release of the first chapter, Greg periodically released more chapters on Patreon. He also uploaded audio of himself reading some of the chapters. The story was complete in December of that year and on December 18, 2018, Greg released Reaper's Creek on Amazon. (Source)
The early chapter releases on Patreon were received with a lot of criticism, particularly in what seemed to be a lack of editing. For example, in the first chapter (as well as others), the main characters' name inexplicably changes from Daniel to Greg. Some of Greg's fans offered to edit his book for free. One comment from his Patreon Beck offering free editing caused a heated discussion in his Patreon comments. (Source, original comment to the right)
On February 12, 2018, Greg responded by rejecting the idea of an editor on twitter, ending the tweet with "I don't play by your rules & if that is a problem: dont fukin reed muh book, thx". He also retweeted a tweet from 2015 saying something similar, originally in response to criticism of his book Stones To Abbigale. (Source) He also retweeted a tweet from 2012 that said "Grammar Nazis should be sent to death camps." (Source)
Later that day, Greg wrote a post to his Patreon that included a video under the title "I Want You To Be Happy". In the post, he explains people are not happy with his book. He wants to make his Patreon supporters happy, but he also wants to continue creating something that represents him and his imperfections. He says if you are concerned with grammar, you can read other books. (Source)Archive under them name "Don't Read Onision's Books". ($ource)
Beck, the writer of the comment, defended herself in the Youtube comments of Greg's video saying she was not trying to be malicious and only wanted to help with his book. She said she felt like Greg's "grammar Nazis should be sent to death camps" tweet was fucked up because she told Greg she was a grammar Nazi two weeks prior. (Source)
Greg responded to the controversy in the video "Onision Virgin? (Virginity Explained)", uploaded June 1, 2019. In the video, he explains people are trying to make it look like he wrote a creepy story, but they don't understand he wrote stories from his actual life. Julia was the actual name of the 15 year old girl he had his first kiss with when he was 11. In the video, he goes into painstaking detail about the sexual experiences he and the real Julia had. He defends himself for writing about it by pointing out he was told there are underage sex scenes in the books "It" and "Game of Thrones". He says if anyone should be called creepy, it would be Julia because she was 4 years older than him. He says he should be considered the victim in the situation by the age perspective, but he doesn't consider himself a victim because it was cool to experience being with somebody more developed than him.
