From that subgenre that defies every "read a historical fiction book" assignment: the time-travel story. Half of it becomes sci-fi and the other half historical. It's been done over and over, but this is better than most offerings I've read. I actually cared about most of the characters, which is always a plus. Mostly very well written, though if I had been the editor I might have suggested pulling extraneous bits--the overbearing mother of a student who had no impact on the plot, for one. Obviously I don't have a whole lot of value to say on this, but I liked it, and that's enough.
