Well I am a total SciFi geek, so it's with great pleasure I can announce that today I found a wonderful compendium of Catholic Science Fiction. It is available in ebook form now and will be in hardcover by april.
Find it at Infinite Space, Infinite God.
Only $5.50 . Read a sample. These Three featuring The Sisters of the Order of Our Lady of the Rescue is a gem.
The section on Catholicism and Science Fiction in the forward alone is worth $5.00.
