In an alternate present where Jewish refugees settled Alaska during World War II rather than Israel, homicide detective Meyer Landsman -- divorced, drinking, living in a run-down hotel -- catches a case in his own building: a former chess prodigy, shot dead beside an unfinished game. Landsman and his half-Tlingit partner Berko Shemets learn the dead man was more than he seemed, connected to a messianic movement within Sitka's Orthodox community, just as the settlement faces a countdown of its own -- its status as a federal district about to expire, everyone's future up for grabs. Michael Chabon's Hugo- and Nebula-winning noir, told as hardboiled alternate history.
