Science fiction and fantasy author Stephen Goldin has launched a plan to give free ebooks in exchange for reviews. The ROGO Program (which stands for Review One, Get One) will give away Smashwords coupons to people who review participating books. In theory, you could get nearly all the Parsina Press list for the price of the first one you buy.
The details and a list of the participating books can be found on
the ROGO Program page. Please note that the rules don't insist on favorable reviews, merely honest ones. If you enjoy reading science fiction and/or fantasy, this could be an incredible deal. Pleasant reading!
