The Friday 56 is hosted at Freda's Voice. Find a quote from page 56.
Check out the links for the rules and for the posts of the participants each week. Participants don't select their favorite, coolest, or most intellectual books, they just use the one they are currently reading. This is the book I'm reading right now:

Book Beginning:
Gustav is building a helicopter. Nobody knows because Gustav has been building it in small sections.Friday 56:
Then the drill bell sounds and the other two coffins open and the entire student body pours out of them. There are twelve hundred teenagers crowding around us, waltzing. They waltz beautifully. The song is Mozart's Waltz no. 1. It is played solely by cellos. This is the waltz drill.Comments: This will be the fourth book I've read by A.S. King. All of them are intense and deal with issues teens are confronting today, even mental illness. The Friday 56 quote is a dream sequence. I think it is funny because we are always doing different types of drills in school (fire drill, earthquake drills, shelter in place drills), so it is funny to think of students doing a waltz drill.
