I can finish a medium-hard 200 page book in about two hours. I can get through a difficult 300-page book (prose) in about five hours.
I can finish the average potboiler book in an hour and a half. The last time I read a book on a flight, I started and finished Tilt by Emma Pattee on a one hour and 21 minute flight.
Sorry about all yโallโs limitations, but they arenโt mine. Not in this realm.
