Read right after re-reading her earlier fairytale novel, Uprooted, and this one is better and more complex, both more historically specific (the status of Jewish moneylenders as related to the Rumplestiltskin myth, the class dynamics of various towns and villages in an alternate Eastern Europe) and more conventionally fairytale-ish, with actual faeries (not called faeries, but a kind of wintry fae called the Staryk) and a cranky demon.

Couldn't stop reading.
