I don't know who specifically wrote the '90 day novel' as there could be many novels created within 90 days by different authors. It could be an amateur writer who was trying out a new writing method, or a more established author who wanted to experiment with a faster writing process.

Since we don't have more details about 'the 5 day novel', it's difficult to determine the author. It could be an indie author who was trying out a new writing technique, or it could be part of a group project where the identity of the writer isn't widely publicized. There are also the possibilities that it's a self - published work by an unknown writer or a new experiment by a well - known author that hasn't been widely reported yet.
