hi mark,i’m curious to know – is this a book you’re self-publishing or do you have a publisher at present to help w/promotions? hopefully you have a website, too – that would be equally (if not more) important to set up than a facebook page at first… it’s your hub and content there can flow into your Page or other social media channels.
there are LOTS of ways market your book, but you may need to be willing to spend some $$ on facebook ads, as well. because of the popularity of this genre, i’m sure you could really get a very targeted campaign going – once your Page is set up and has a clear strategy (which needs to be guided by you). 
i would also highly recommend looking at some other big name author Pages (or personal profiles) to help you crystallize this. What are they doing that you like? Or not? What types of posts are they creating that get lots of engagement and how can this translate to your topic?
does your book already have a cover? if so, BIG cover image – especially if the art is good. if not? some really strong sci-fi art that reflects your topic – even if you pay a small licensing fee for it… have you written other titles? are you an avid sci-fi reader yourself? are you currently writing another book? 
i’ve been in the book industry for 2…let’s just say a LOT of years : ), and can attest that authors MUST be proactive in promoting themselves even if they do have a publisher! it’s a valuable skill to learn and hone and will only serve you well. 

@markoetjens – I’ve done book PR for a long while (clients inclue NY Times bestselling DUNE co-author Kevin J. Anderson and horror writer L.A. Banks) and I can provide you with more advice than you can digest on this topic. #1. Do you have endorsements from respected sci-fi authors? Did you sent out review copies to respected reviewers? Do you have reviews on Amazon?#2. @pegsousa is right about the cover art. My husband Dave Dorman is a cover artist for sci-fi, horror and fantasy books and many reviews mention his covers as the selling point for these genre books. If your book has spot illustrations amongst the prose, it’s a graphic novel and that’s another audience for you.#3. I would recommend you get into the LinkedIn Groups for your genre and also the graphic novels/comic book creators groups on LinkedIn because they will appreciate your genre of writing. #4. Do you have this book for sale as an eBook online? If not, go to Smashwords.com and get it in every format iteration (outside of Kindle, which is a separate site). Do you have a press list for reviewers of sci-fi books? #5. Are you Tweeting and using the sci-fi hashtag so people searching for sci-fi can find you via Twellow and the Twitter search engine?#6. Have you set up an author profile for yourself on GoodReads.com and sites like it?

There are some newsletters you should really start subscribing to – Book Author Marketing by Penny Sansevieri is one of them, and Noel Griese’s Southern Review of Books is ideal for really knowing what’s going on in the book trade.

Feel free to ask me questions.

@pegsousa @denisedorman The book is self-published… kind of. I started my own publishing co. to publish my work. I hope to eventually expand into publishing other authors in the future. I’m using the company website http://www.conquerpublishing.com as my base of operations. I’ve done a blog tour. I already have a professionally designed cover (my best friend is a graphic designer). The book is available through all the major online bookstores (Amazon, B&N, Books-A-Million). I do have reviews on Amazon and B&N. For ebooks, I use Smashwords (I love them!). Reviews there, too. I’m on Twitter and recently I started accounts for 2 of my main characters. But I’m not using Twellow yet. I’m in several pertinent FB, LinkedIn and Goodreads groups but I admit I’m just now starting to participate in those groups. From your responses, I think I’m starting to do most things right. But like I said, FB is changing so quickly, especially with the timeline, I’m just not sure.

yes, it sounds as if you are! i think the Page and personal profile changes to Timelines are of great benefit to “creatives” (writers, artists, musicians) you can do a lot of fun stuff with the milestones to help tell your story – including character development etc.  i think what you probably face more is how and where best to spend your time! and that kinda comes with by doing it and seeing what works best for you. there really is no ONE way to do social media right but rather a million and one ways. but coming to boards like these most certainly help you learn about new tools and best practices and time-savers.
