The Fuller Memorandum

Stross's third Laundry novel (after 2006's The Jennifer Morgue) continues to describe the Kafkaesque absurdity of government bureaucracies, but the tone turns dark when series hero Bob Howard accidentally kills a civilian during a routine exorcism. Bob soon discovers that there's a mole loose in the Laundry, the ultrasecret British intelligence service that deals with the implications of magic being a branch of pure mathematics. At issue is a memo by the Laundry's founder that relates to something called the Eater of Souls. The only person who knows anything about this is Bob's enigmatic boss, Angleton, but when he inexplicably vanishes, Bob and his wife and fellow agent, Maureen, are left on their own to stop CASE NIGHTMARE GREEN: the end of the world. The satisfying ending should appeal to fans of gory horror while making them question the definition of humanity. (June)
