I just got this as one of my Christmas presents and inhaled it at one go before the afternoon was over - it's a fabulous book. Now I have to reread it more slowly, so I can appreciate it differently.
In its sidelong view of memory, I was very much reminded of Mr. Punch, which I now really want to find a copy of and reread.
(Also got Gene Wolfe's A Land Across, requested on the strength of the excerpt at Tor.com. A very odd and elliptic book, oddly colored by its narrator's viewpoint, but I'd expect nothing less.)
