Joan Didion, the revered author and essayist whose provocative social commentary and detached, methodical literary voice made her a uniquely clear-eyed critic of a uniquely turbulent time, has died. She was 87.

Didion's publisher Penguin Random House announced the author's death on Wednesday. She died of complications from Parkinson's disease, the company said. 

"Didion was one of the country’s most trenchant writers and astute observers. Her best-selling works of fiction, commentary, and memoir have received numerous honors and are considered modern classics," Penguin Random House said in a statement.

Her essay collection "The White Album" has become standard reading and "Slouching Towards Bethlehem," and "Play It As It Lays" became essential collections of literary journalism.
