Sixty-four hours and forty-six minutes is the headline figure, narrated throughout by Mark Boyett. A single voice across a run that long becomes part of the furniture, which is either the appeal or the deciding factor, depending on how you listen.
The score is encouraging, though it rests on a modest number of ratings, so read it as a nod rather than a consensus. This one is scheduled rather than live, so it will appear once it lands; if a saga you can start and finish without interruption sounds like your idea of a good month, keep an eye on the audiobooks gathered below.
