Got contacted my another person who received my book as a door prize at a church function. She'd liked it enough, she's going to buy the sequel.
I wish, and you'd think that as a writer I could, find the words to describe how you feel when you get an e-mail from someone who enjoyed your book. It's like Christmas. A huge feeling of euphoria. It gives you that boost you need to keep writing when the rejection slips from the big publishers fill a file folder in your desk drawer.
If someone likes your first book, when you really didn't know much about writing, how much more will they like your fourth, when you've learned so much.
