Looking at your blog it's still pretty new. It can take a while for Google to index the pages - up to a few weeks or maybe even longer if you're unlucky. It doesn't seem to be indexed yet, in any case.

What Vyk meant was probably that you can add "site:livejournal.com" to your search to only get hits from that domain. If you want to search for several words in the order you put them, put double quotes around them. A good search to locate your blog (when it's indexed) would probably be: site:livejournal.com "your book name"
