The first was my 3rd annual appearance at a local book club. They read my book for a select month each summer and then I come in to discuss it. It's mostly retired-age people, and they (and I) always get a kick out of the whole thing. It's really neat to talk about your book - your characters, your plot choices - with readers. I love their questions and their observations too.
The second was a reading/discussion at a local library. While not very well attended (about 6 people), the ones who were there asked good questions and were mostly writers, so they were interested in my process/the publishing industry as well. Even better, the librarian asked if I'd be interested in coming back to run a half-day writing workshop - and how much I charged! I've said it so many times: you never know how networking and making public appearances will affect you later down the road. Do it! Take advantage of people who want to hear about your books and your writing!
