Maxim hat The Space Trilogy von C. S. Lewis besprochen
Christian space opera
This one is difficult to rate because I don't know what to compare it to. The Space Trilogy is not sci-fi as the title might suggest, nor fantasy like The Chronicles of Narnia. In fact it is a rare case of Christian speculative fiction.
I was surprised to learn that Clive Lewis was a theologian and an active preacher. Can't recommend the book to atheists/agnostics but wholeheartedly recommedn to anyone looking to find Christian values in a fictional world.
