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 Beginnings:
Lydia is dead. But they don't know this yet.Friday 56:
Most missing girl cases, the older policeman tells them, resolve themselves within twenty-four hours. The girls come home by themselves.Comments: The Friday 56 quote is from some random page, I can't even tell which one. I am listening to the audiobook so I had to pull the quotes from a sample on the Internet. Obviously from the two quotes you now know that Lydia is dead, possibly murdered. What the reader doesn't know is very much about the girl and then family figures out they don't much about her, either.
