You can read the original letter here.
I forgot to mention that publishers, for the most part, do not take on books that have already been published. And agents think the same way. If your book is selling maybe 1,000 copies a day (or even 500), and all by word of mouth, then they’ll knock down your door to sign you up.
I don’t know if you are in the process of writing another book, but if you are, you might want to save all that energy and work sending out your query letters for the new book.
You probably already know this, but there are sites that will teach you how to write a dynamite query and their members will critique it for you and add advice. That’s what I did. I think the site’s name is Agent Query. They also have up-to-date lists of agents to work from when sending out your letters.
Finally, have you ever thought of doing paid promotions with the likes of eReader News Today, Choosy Bookworm, or Free Kindle Books and Tips? For $30.00 or $40.00 they’ll send out an email to their thousands of subscribers and you’ll get some sales. You’ll have to drop your price to $0.99 for the day of the promotion. Remember, the more books you sell the more reviews you’ll get, and the more reviews you get the more books you’ll sell. I never give my books away for free. When people get books for free, many of them stick it on their Kindle and forget about it. But if they pay for a book, they’ll read it. Even if the book was only $0.99.
