Is that religion in my science fiction or science fiction in my religion? The writers of the Catholic SF anthology Infinite Space, Infinite God (available at Twilight Times Books) have so seamlessly combined the two that it's hard to tell.
Infinite Space, Infinite God features fifteen stories about the future Catholic Church: its struggles evangelize aliens and lost human colonies and to determine the soul-status of genetically modified humans, genetically-designed chimeras, and clones made from the Martian sand; the adventures of religious orders devoted to protecting interstellar travelers or inner-city priests; and how technical advances allow monks to live in solitude on the Moon and help one criminal learn the true meaning of Confession.
But it's more than just a great read. With introductions exploring the issues at hand and current Church thinking, Infinite Space, Infinite God is bound to spark discussion and make people think--just as good science fiction should.
