Yes, three years ago my friend and I wrote a short book in LATIN based on Sallustius' 'De coniuratione Catilinae' called 'De coniuratione Iustinis' and it basically tells the story of those men who back in 2012 tried to kidnap Justin Bieber and castrate him
Other books (in Italian) we plan to write/have started together are:
- 'Tu, io, il Capitano e Anita' ('You, I, the Captain and Anita'), where Anita has dreams at night that are going to come true the day after.
- 'La deplorevole Anita' ('The Despicable Annie'), the follow-up to the first book, and it sees the sweet Anita going evil and attacking everyone, but eventually finding her way.
- 'La russa, la bielorussa e il prete' ('The Russian, the Belarusian and the Priest'), which is about me and my friend enjoying our morning at a cafe and seeing three teenagers sitting at a table. We start to think of what their life stories might be.
- 'Il culto del barboncino' ('The Poodle Cult'), set in the early 20th century New York City, where all the upper class families own a poodle. A poor family from Oklahoma moves there with their poodle and they become rich thanks to it.
- 'Il cardinale itinerante' ('The Traveling Cardinal'), which is about a Vatican Cardinal who learns from Jesus that his mission in life is to find out where Santa Claus is in summer. After traveling around the world with a crazy ass sister, he finds Santa in Bangkok looking for prostitutes and drugs, partying hard and getting drunk.
When I went to college I received my degree in history with a minor in creative writing, but I have quite literally never done any creative writing unless it was assigned by a professor. 
It comes from a childhood of watching Twilight Zone marathons with my dad.
