Last week I gave away two copies of my paperback, one on Goodreads, and one to friends and family. I was afraid that they might be won by people who only like free stuff and end up on backshelves somewhere, never to be read. I can happily say that both when to very excited readers, one of which was my HS teacher. We met, had coffee, and caught up. It was fantastic!
The giveaways also gained a decent amount of publicity, including the 500 people who entered the giveaway on Goodreads.
