A difficult book to rate. London came through clear and vivid, and I loved the protagonist's voice, snarky yet sincere. The hints of deeper worldbuilding were just enough to catch my interest and keep me speculating.
. . .all of which almost makes up for the fact that there is, at most, a short story's worth of plot here. Okay, maybe two short stories, but they never intersect in any meaningful way.
And yet I don't care. I read long after I should have put the book down to do other things, waiting to see what just one more page would bring. I've got the next book already in hand, and I look forward to seeing if Aaronovitch has learned how to plot since his debut effort--but I'm pretty sure I'll enjoy it even if he hasn't.
