You wrote a book, called a bookstore, booked a signing, purchased a roundtrip AMTRACK ticket, packed your overnight bag because "traveling far and light" is the rule Mama Disilgold taught you and now you have arrived.
You weren't able to get a local radio show to interview you on the commute, gain a poster or marquis ad a week before your signing or advertise in a local paper. You're hoping the local bookclub you personally contacted or sponsored with free book giveaways prior to the event will arrive to support and take some photo ops for your website updates.
Sorry, you are leading a non-productive media campaign headed toward failure. Allow me to share how to make your signing productive and successful!
