Thank you for signing up. Your free book will be with you momentarily, but
BEFORE YOU GO...
Make sure you go to your email and validate your email address. You know, just in case this was a 3am pizza indulged decision that you now regret. (Who regrets pizza at 3am? Nobody. Who regrets it the next morning? ... I'm still going with no one, but you can't be sure.)
Once you've validated your email, your free book will be flying over.
