I have a copy of Go Ask Alice, though I've only skimmed. But I've read reviews of the new book just out, Unmask Alice: LSD, Satanic Panic, and the Imposter Behind the World's Most Notorious Diaries, and I'm eager to read it.
At Quillette, "Go Ask Beatrice: Notes on a Dishonest Decade."
"Beatrice" is Beatrice Sparks, the notorous Mormon youth counselor and inveterate hoaxer.
