What has the author Robert Dreeben written?

It seems you're asking about an author named "Robert Dreeben." While it's possible there is an author with this name, there's no widely recognized author by that name in the literary world.

It's likely you might have a slight misspelling or that this author publishes under a different name. Could you please double-check the name or provide any other details you might have, such as the genre they write in or the title of a book they've written? This would help me find the correct author.
