Ah, very good! Now we're talking about the right thing. We're in the right arena.
Re having your whole book on your blog, I'd take down most of it and start over (with putting it up on your blog, that is, not writing it.)
First, I'd put up some testimonials by people who've read it. Like me, for instance. "'This is a *good* book!' Barbara Sher, author of [whatever you think is my best known book]
Then a few paragraphs of the beginning. And I'd stop on a tantalizing sentence. "He looked up and couldn't believe his eyes." for instance. Then skip some spaces and say, "It will astonish you. Go to the next blog entry and find out now!"
Then, in the next blog entry I'd put a chunk of the novel, not more than a page or two, and stop at a logical pause, skip some lines and say, "If you're enjoying my novel, click here to get the next chapter, free. Or click here to get the whole thing for 99c. And thank you, dear reader. I hope you'll enjoy the very unusual story you are about to read. And I'd love to read your comments."
Then I'd go to Twitter -- and you'd better stop complaining about Twitter or you'll get an earful from me. It's a lot better than you understand, but even if it weren't, if you want people to read your book, you go to Twitter.
First I'd take the URL of the blog entry and take it to bit.ly and make it short. (Try it. It's easier to do than to explain. For instance, the URL of the page I'm typing on right now is: posting.php?mode=reply&f=27&t=25313
And after bit.ly, it's only: http://bit.ly/U1ZRdv
Leaves you more room to say exciting stuff, like:
"He couldn't believe his eyes!" What did Bill see? Look at the opening of my new novel to find out: http://bit.ly/U1ZRdv
You might get a few sarcastic comments, but, for the most part, the only people who will see your comments will be us, because I have a hunch no one is following you.
In fact, *I* might get a few sarcastic comments for suggesting something this obvious. But there are very smart people who do far more:http://www.copyblogger.com/smart-people-headlines/

Oh, and by the way, start reading ProBlogger, and other blogs about how to get your novel noticed.
Any additional suggestions, fellow amateur marketers?
