Over at Reddit, one user asked an excellent Friday question: What’s the best book you’ve read in a single day? Add your favorite one day book in the comments section or share it on Twitter with the #1DayBook hashtag.

So far, the question has generated hundreds of responses. Below, we’ve collected some of our favorites. This GalleyCat editor will never forget reading South of the Border, West of the Sun in one heady day in college.

Check it out: “What’s the best/most unusual/longest/most enthralling book you’ve read in a day? DON’T SAY HARRY POTTER; we’ve all done that. Mine? The Third Policeman. I read it in a trance in the Dublin airport when a blizzard was keeping me from getting home. It’s a surrealist horror story.”
