I can read a 300 page book in a day between commuting and evenings but like has been said, you never really get into the book fully and some do take longer because I am enjoying it so much. I doubt the books she is reading is that taxing and so that number can be right, but she will learn that a look of people in the bookstagram world like books and reading and is not trying to hit an impressively high number. They do proper reviews and code their books and re-read them over and over. Its just another fad she is getting caught up in in the hopes of being noticed again and maybe get a freebie or 2
