If you're referring to "Angels and Demons", the best-selling prequel to "The Da-Vinci Code" by Dan Brown and the associated movies, then yes. Dan Brown's been mocked pretty widely for both content and writing style, but he's still insanely successful.
If you're referring to something else, then I'm not sure what it is.
