Often us readers enter a trance and the book which we’re reading is the only thing on our mind. I used to be like this with most books when I was in middle school but now due to academic pressure I do not invest my entire time to a book. Lastly, the Divergent trilogy took me the shortest time to complete- I finished the entire series in three days.
I read about half of Robert Jordan’s Eye of the World (Book 1 of Wheel of Time) in about 9 hours. I was around 14 and I went to bed at 8pm and read straight through until 5am. I remember this clearly because Dad woke me up 30 minutes later to force me to go fishing for the day.
