Oh, I like this idea. Renee at Renee's Book of the Day is seeking contributions for a new book review podcast. Her podcast, Renee's Audio Book Club will feature reader reviews and she promises to credit you if you leave your name. Call the number to review the work; read a passage; give your reaction.
The first book is Kazuo Ishiguro's Never Let Me Go. There isn't a set deadline yet, as she is working through some technical details. I hope there is a regular schedule for submissions and air dates once she has this up & running.
