Here's what to say when you e-mail:
- Tell me who you are.
- Tell me what you've written/produced (including the genre).
- Send me a link to your site or the book on Amazon or whatever.
I'll take a look and let you know whether I have the time and/or interest in reviewing your stuff. Don't take it personally if I don't or can't. I promise you don't want me to review your book or CD if I go in already thinking it's not my thing or that it's sucking up my time.
Also, just to be clear: my accepting something for review doesn't mean I'll give it a good one. I make it a point to remain honest in all my reviews.
Best of luck.
