A curious mashup of genres that doesn't quite come together. Killarney is a master agent for a British spy service, except their brief is not human enemies, but angels; the angels have come to Earth at the end of WWII and become another element in the global Cold War power game and its associated espionage.But while Killarney appears be a super-agent à la James Bond, she narrates the book in first person with the blunt, simplistic, repetitive sentences appropriate to the hard-boiled genre. (It doesn't help that the audio narrator has a fairly upper-class English accent, or at least it sounds that way to these American ears.) Sentences are short and often begin with "and"; adjectives are few; the most obvious words are used, even if they've just been used in the previous sentence. There's no trace of the suave Bond kind of agent; Killarney throws punches, breaks bones, wipes away the blood, and moves on.And beyond the setup and their insertion into some standard (human) goodies vs. baddies conflicts, the whys and wherefores of the angels just aren't clear. Maybe if I'd read Paradise Lost more recently?In addition, the recording quality of the Iambik audio edition was often thin, tinny nearly to the point of being grating.All in all, I was kind of relieved when it was over.
