The first, The Yiddish Policeman's Union by Michael Chabon, actually won this year's Hugo award, as it was an alternate history novel. I found it interesting, in that the Jews that survived the Holocaust, had been driven out of Palestine, and had ended up in their own refugee zone in Alaska. This seemed to me to be a curious turnabout, in comparison to what actually has happened. The book deals with a murder investigation in a place of much upheaval, as the US prepares to close the refugee zone, putting the Jews of the region to flight. Might be worth a look-see, if you like alternate history works.
The other book was Sandra Tsing Loh's Aliens in America, which I may have read previously and not recalled. It's a series of short stories about her family: a Shanghai Chinese father, a German mother survivor of WWII from Danzig, and her elder sister. There's some humor and a little pathos here, and it's a rather short read.
