Actually, two of them run blogs and have read (and reviewed) the whole trilogy now. I am finding that for an Indie author, such as myself, these blogs are an incredible way to promote and get exposure. Goodreads is another great way.
I finally clicked on the 'run a book giveaway' button on Goodreads and went through the motions. Basically, you put up however many copies you want to give away of your paperback (or hardback) book and set the time period, etc. (I also limited mine to the States. You'll want to do this too, depending on what country you're from. Overseas shipping is VERY expensive!) With Bloodline, I ran it for about a month and had over 700 people enter! Of those, about 400 of them added Bloodline to their bookshelves, which then in turn exposed it to all of their friends. (which in some cases, is thousands) So while yes...most of the people entering probably just go for the free books and rarely actually buy them, I think that it did generate a few sales and more importantly, gave me some great advertising. I gave away four copies of Bloodline (extras I already had) and the shipping was $10.00 total. (be sure to go USPS with the book rate) Bloodline is now spread out across the East Coast, being read by people who would probably never have done so otherwise. Who knows? Maybe they'll like it enough to either write a review, read the next book (Heritage) or even better...give the copy to a friend!
Heritage is in a giveaway right now:link
It's been just over two weeks and over 100 people have entered. I just put up Descent also, to give away two copies, and in only four days, almost 80 have signed up. I take that as an indicator that the cover for Descent is maybe the one that grabs the reader the most. I would have to agree. Who doesn't want to look inside when they see a young, strong girl holding a automatic rifle on the cover? :)
Here's a link to the reviews for Descent:

I'm going to include here, a review from a reader from Goodreads:
