this has been a subject of interest of mine for several years, so i'm looking for recommendations & to compile a decent list of related books.
looking for fiction & non-fiction (memoir, true crime, etc.), although not interested in cult psychology books unless they're particularly good.

Have you read Blown for Good: Behind the Iron Curtain of Scientology, by Marc Headley? It's a really interesting view behind the scenes of Scientology.

K.t. rose - the silent red room

Some books about Hubbard and scientology -

Bare-faced Messiah by Russell Miller.
A Piece of Blue Sky by Jon Atack.
Battlefield Scientology: Exposing L Ron Hubbard's Dangerous Religion by Paulette Cooper and Tony Ortega.
The Unbreakable Miss Lovely by Tony Ortega.

Oh yes, nearly forgot -

Ron The War Hero: The True Story of L. Ron Hubbard's Calamitous Military Career by Chris Owen.

Last Days by Adam Nevill

Essentially a book about a documentary team studying an infamous cult from the 70s.

Slow-burn but Supernatural Horror

I could write for days about this, but I'll just drop two:

Bagwhan: The God that Failed by Hugh Milne. Very interesting, insightful stuff on the Orange People.

Jesus Freaks by Don Lattin. All Don Lattin's books are great, but this look at what happened to the child of David Berg, raised in his father's sex cult, is a terrible tragic story.
