In his late forties, his once blonde mane has turned mostly to gray, though he still has a young and spirited way about him. Jonah Kensington is the owner and editor at Prospero House. In addition to being a close friend of Jackson Elias, he edits and publishes Elias's books.

Prospero House is a publisher of books having occult or fantastic themes, fiction
and non-fiction alike. The modest concern does not aim for best-sellers, an almost unheard of concept by the end of the millennium, but rather for books which deserve to be published because they will interest select readers for generations to come.
