Your challenge, if you choose to accept it: Pick any book from your readathon pile and write a fake synopsis based solely on the cover. The synopsis does not have to be related to the actual book at all, just the pretty, pretty cover.
My entry: A Matter of Class by Mary Balogh
The lady was lost. She had wandered too far away from her country home and found hereself in a barren land. There were a few trees, but nothing to really give her cover. Her white muslin gown wouldn’t last much longer in their wasteland. Her only hope was that her magic parasol would send an SOS beacon to her knight. He would figure out a way to rescue her. Until then she was stuck!
