So much to love about this book, how it weaves together unanswerable questions about consciousness and computation, together with a much more didactic message about humans' consumptive relationships with, well, everything including each other, and enough of a mystery story to keep the plot moving along. Also some great evocations of places (ahhh, multiple key scenes on Istanbul ferries), and of the ways peoples' reputations misrepresent their selves.

It's not a strongly character driven book - every character that is fleshed out seems to be a variant of "loner who wishes for connection" and largely a vehicle for the author's ideas - but there's enough depth to the characters to keep me reading. My one real criticism is that the ending felt a bit rushed. Not in the sort of too convenient, story-undermining way, but not quite satisfying either. It doesn't feel like a set up for a sequel, but I kind of want Nayler to write a few short stories filling out the characters a bit more and picking up some of the loose ends - perhaps something like Sofia Samatar did with The Winged Histories.
