Just out: Frances Hardinge's _The Lie Tree_ (2015). I'm not sure but the print form seems to be only available in large paperback, not hardcover. Oh well, it was a gift and I'm not complaining. Avoiding spoilers: it's set in the early Victorian era, and it is good solid YA. It doesn't seem as complex as her earlier books, being possibly more akin to Dodger than to Discworld. Even the paranormal aspect could theoretically have been written out, though I'm not sure what could have been substituted for it. The complex culture is that of the Victorian era with its layers of unspoken expectations according to rank, class, clothing, age, perceived wealth or poverty, manners, etc. I am extremely glad I don't have to live in that culture.
Now to wait until she gets another one to the publishers.
