Castalia House Non-Fiction is presently divided into two categories, esoteric and educational. TRANSHUMAN AND SUBHUMAN: Essays on Science Fiction and Awful Truth, by John C. Wright, is our first published non-fiction and was #1 on Amazon in the Science Fiction History and Criticism category. In the educational category, Castalia House publishes ASTRONOMY AND ASTROPHYSICS, a high-quality homeschool curriculum authored by Dr. Sarah Salviander.

Castalia House will be publishing more non-fiction books on military history, economics, physics, philosophy, and other subjects later this year.
