Grant claims to be the true successor to Aleister Crowley and his order to be the true OTO.
He was a great admirer and close friend of Austin Osman Spare and did much to bring his name into western occult society.
Many of his ideas, such as the use of H. P. Lovecraft's mythology, are highly disputed.
He published nine books in three trilogies (the Typhonian Trilogies) that span a vast number of topics. Titles include:
- The Magical Revival
- Nightside of Eden ISBN 1871438721
- Outer Gateways ISBN 1871438128
- Remembering Aleister Crowley ISBN 1871438128
- Hidden Lore: The Carfax Monographs by Kenneth & Steffi Grant
- Outside the Circles of Time
- Cults of the Shadow
- Hecate's Fountain
- Images and Oracles of Austin Osman Spare
- Beyond the Mauve Zone
- The Ninth Arch
- Zos Speaks! (Austin Osman Spare work)
