Gary Mugford at Mugshots gives MR. MONK IN OUTER SPACE a thumbs-up. He says, in part:
Goldberg has lots of fun at the expense of the typical SF convention-goer, but there seems be a respect deep down. […]But it’s really almost an Ambrose book. It’s Ambrose who provides the needed insight into the TV series, since he’s an expert on the show. It’s little insights into Ambrose that makes this something different rather than the same old, same old. That’s why this book gets a thumbs up. Goldberg continues to expand the tight little world that is Adrian Monk. As we head to the eighth and final TV season, it’s going to get harder and harder to find new sides to the mystery that is Monk. But for the time being, Goldberg continues to deliver solid entertainment in new and surprising ways.
