Audiobook, narrated by Gideon Emery.
The fourth Laundry novel. Stross has fun linking fundie Christianity with the worship of unspeakable horrors from beyond the stars, but the expected chills aren’t really as apparent as in The Atrocity Archives and The Fuller Memorandum.
It does seem that Stross is going to go through with the endgame of CASE NIGHTMARE GREEN (aka The End of the World) as the series goes forward.
