Your best bet is Amazon. I've published 18 novels through them and I make a good living with my books. Traditional publishers are getting harder to snag, so alternative venues are a great way to get out there. Avoid the "Pay For Play" publishers. They take your money, send you a copy of your book, and leave the marketing to you. Amazon gives you that same option without the high cost, and you get to price the book how you want it.
