Giveaway contests are usually run two weeks before a release exclusively for mailing list subscribers. If you need to purchase the book through Amazon, please locate the book you were trying to win here.
If you’d like to participate in an early release giveaway and you’re not already on the mailing list, please join the mailing list so you’ll be notified of the next one.
