He's the author of Book of the New Sun, which is massive but which I just finished and which is incredible, full of implicit Catholic theology, Greek philosophy, and mythology. Some of his biggest literary influences were Chesterton and Tolkien.
He's also a convert, whose conversion followed the same path of TDE's main scribe, Eric Scheske, who also undertook a sincere study of Catholicism after getting engaged to his Catholic wife, though Scheske's conversion came in his mid-twenties:
Wolfe grew up a Presbyterian, but began to study Catholicism in the mid-fifties so that he could marry his wife, Rosemary, in her church. During the course of his instructions, he found something that resonated; he converted, and his faith remains deeply important to him.
