I just finished
Household Gods by Judith Tarr and Harry Turtledove, about an attorney and recently divorced single mother who gets sent back in time to a town in what’s now southern Austria during the reign of Marcus Aurelius. I’d never read either of them before, but this was really well-written— up until the ending.
As I said, the rest of the book was fantastic. Whichever of the two didn’t write the ending I want to read more of, because they’re very talented. And whoever did write the ending ought to be ashamed of themself.
