The Friday 56 is hosted at Freda's Voice.
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:
The boy inhaled as the door opened. It was as if he knew. The girl stepped into the room, and within the space of a heartbeat, he was lost.Friday 56:
Green Lantern, thank God, had a superior story about having to keep driving back to a school crosswalk several times a day, all week, because he was convinced that he had run over someone last Tuesday...Green Lantern listened to newscasts on the radio and TV, read for a report of an accident on the corner of Chestnut and Walmer. Nothing.My Comments: I just finished the book yesterday and enjoyed it quite a lot. The main characters are part of an OCD support group. Their psychologist suggested that they may do better in treatment if they take on a superhero alter ego. The main character is Batman, his love interest is Robin, and others are Green Lantern, Wonder Woman, Thor, etc. The book is surprisingly thoughtful and touching.
