It's All Real - A Patrick Hockstetter book

Solipsism- the view or theory that the self is all that can be known to exist.

15 year old Patrick Hockstetter is the psychopath of Derry, Maine. He's friends with Henry Bowers, Reginald "Belch" Huggins, and Y/N's cousin Victor Criss. Patrick acts like he doesn't care but in reality he would do everything in his power to protect you. You are friends with the losers club and sadly have frequent run-ins with your cousin and his delinquent friends. Even though Patrick thinks everything around him isn't real he makes an exception for you.

Edit: I don't own any of Stephen Kings characters and this is just for fun the only character I own is Y/N just to put that out there
