Briefly: you pay whatever you want to get an amazing collection of Science Fictions titles from Open Road! A percentage of your payment is donated to charities (First Book and the Science Fiction & Fantasy Writers of American Emergency Medical Fund). My most successful novel The Reluctant Swordsman is in there, plus notables by umpteen top writers.
