Shatterproof is an organization that helps people in recovery from addiction. I have signed on to help them raise money from sales of Detroit Muscle. If in the next 204 days, you purchase a copy of Detroit Muscle from the Paypal button on my website for fifteen dollars, $3.00 (or 20%) of that purchase will be donated to Shatterproof. (I can't honor the donation for overseas shipments because the postage will be too much)
Your fifteen dollars gets you a signed copy of Detroit Muscle, shipping, and the good feeling that comes with knowing that a portion of your purchase is helping to fight addiction.
You are welcome to make a donation to the fund drive, too.
