I found a book! There was a bookmark inside with a "referred by GlacierGirl" at the bottom... there was a yellow post-it type note inside the front cover... but no identifying number or code to be able to track the book!
I'd like to find out what the book should be identified as for future readers!

The book is "How Stella Got Her Groove Back" by Terry McMillan. It was discovered in the Market Building in Olympia, Washington USA...
My first introduction to this wonderful idea and hopefully the first of many books that will pass through my hands!
