I love indie bookstores :). I "stole" the original idea from a fantastic indie bookstore that I stumbled into.
I walked into the bookstore, and they had little index cards to show off staff favorites and a little half-tweet on why: "Andy loves the characters in this outside-the-box fantasy series;- you will dig it."
It was this magical way to meet the books. I thought it would be fun to try to do that while helping authors meet readers.
