In order for you to get your site and your work noticed. You need to all have good do follow backlinks. Here is a link where you can get up to 750 a month by promoting your blog, site and book links on social networks. Trust me, this will help you achieve the links you need without costing you a penny. I use this service amongst others and i would be happy to share my knowledge to help all authors here.
Just a tip though, build it slowly to achieve a better linking platform and so that you will not get penalized. This is more natural. Share a link every other day.
