Well, libraries have taken that idea and put a little twist on it. It's called Read it Forward. The library buys copies and hand them out to students to read. Each book is numbered. After reading the book, the students go to the website and give their book number, their first name, location, and comment. They are to then asked to pass the book on to someone else. With luck, you can track where each book goes.
And it sounds like the good folks in Taylor, Texas are doing that with Shock Point in advance of my visit there the week of October 15. This is really thrilling.
(Full disclosure: and if you know a school near Taylor that would like to have me present to them Oct. 18-19, let me know ASAP!)
