The author of The Locked Tomb trilogy, to which I had the following reactions after my first read:

• Gideon the Ninth: That was pretty good, I want to read the sequel!
• Harrow the Ninth: That was... really confusing but excellent, this has definitely joined the list of my top sci-fi series.
• Nona the Ninth: These are my favorite books.

I have gone on to read several other works because Muir cited them as influences, including but not limited to: Homestuck, Dream of the Rood, and The Last Unicorn.

I could go on for a very long time about these books and probably will soon, but to try to make a series of short pitches: A study of different kinds of love and devotion, by way of Warhammer 40,000. Casual references to the epic poetry of Homer, Anne of Green Gables, and none pizza with left beef, among others. The most Catholic fiction I have ever read. An existence proof that books do not need to contain any actual content that is remotely sexual to be wildly horny. The phrase I now use to express why I hold my religious beliefs, in a scene that still makes me sob. A "cool S".
