For obvious reasons JRR Tolkien is the go-to Catholic fantasy author, as his works are rife with Catholic themes and ideas. As I'm reaching the end of
Return of the King, and looking onward to read the
Silmarillion, it makes me wonder if there are other good authors of fantasy which utilize Catholic themes in a similar, mature manner as does Tolkien?
I've come across "political philosopher/commentator" Vox Day's
Arts of Dark and Light series, which utilizes an overtly Catholic culture as the centerpiece of his fantasy world. And I've begun reading
Summa Elvetica: A Casuistry of the Elvish Controversy, and find it pretty engaging in its own right so far. I have no idea if he is a Catholic, but he certainly has a good grasp of Catholic culture and themes to make his world convincing.
Yet I have trouble finding others that are worth the time. Perhaps some here would have suggestions of series or, individual books, in the high fantasy genre worth reading?
