Nice!
Props on you for being able to wait to start MS after reading that banger of an ending in GS. I remember immediately buying MS that same day despite having originally planned to read something else in between the two books lol.
And thats the worst book of the series, by a decent margin.
Fwiw, Martian Reds are the descended form Irish survivors who'd fled the Isles after the events of WW III because they were rendered radioactive. Hence the choice of accent for the AB reader.
They've also got Graphic Audio books. These include proper sound effects and a full cast for each characters. Their tagline is "a movie in your mind".
Pretty good production value, and not just for the RR series.
Also, some big news came out a couple days ago.
