"Great voice adds to already amazing story"
Of course, "Good Omens" is an easy choice for any shopper. If you haven't read it before or especially if you have, the audiobook is a pleasure to listen to!
Once I heard Martin Jarvis reading in the character's voices, I can no longer imagine their voices any other way. Jarvis hits the nail on the head with Aziraphale's mild personality and Crowley's "flash bastard" attitude.
My only problem is the lack of a distinct pause between scene changes. As the book does this often, I quickly got used to paying attention to the new scene. It would certainly not dissuade me from buying the audiobook.
