Where can I advertise my novel?

[Bri Nicola]

Before I start, I'd just like to say that leaving this to the last minute wasn't a good idea XP
Ok, I'm going to assume that you have been published, or have self published.
Make a Facebook page, blog, and set up a twitter feed. Whatever the targeted audience for your book is, find a book group that is of that audience and tell them about your book. If you don't mind taking a chance, if you give a few people who are members of large book groups a free copy of your book, you should get some more sales from word of mouth.
The first four or so I suggested cost nothing. Here are some that cost a bit, but may be worth it:
Take out a Facebook ad. You can target a specific audience, and you choose how much you are willing to bid for each click. There is a lot of control with this option.
Take out a Google ad. Not as sure on how this works, but if you go to the bottom of the Google home page you will see Advertising Programs Business Solutions About Google. Click on Advertising Programs and you should be able to get the information you need.
I hope this helps! Please note that I haven't tried any of this yet, but am publishing Wizards' Quests-Angels-Traitor, my first book, in a few months. Depending on if anyone hears about it, the plan I suggested here may be the best or the worst. I guess we'll see.
