Dark World, Book Eight of the Xandra series

I finally managed to find the time. I published the eighth book of my Xandra series today with Smashwords. 'Dark World' is actually the continuation of Book seven 'Alien World'. I set the price at $2.99. I also changed the price of 'Alien World' to $2.99. It just wasn't selling. I'm very disappointed. After all my hard work. I think it is a good story, written, of course, for people who love Science Fiction and a little Erotica. Unfortunately, there are so many books available these days and the problem is to get readers to notice your book. Perhaps the new price will encourage readers to buy it.
