A Plague on Both Your Houses by Robert Littell

A brand-new novel from New York Times bestselling author Robert Littell, A Plague on Both Your Houses is a thrilling tale of love and war.
On Christmas Day, 1991, Mikhail Gorbachev delivered a ten-minute televised speech announcing his resignation as Soviet president. Moments later, with little pomp and less circumstance, the red flag was lowered from its floodlit perch atop the Kremlin, and the Soviet Union ceased to exist.
Into the vacuum-before a new demacy had time to put down roots-surged the Russian mafia, supplying what the new state could not: krysha, or "roof"-protection for the privately owned businesses sprouting across the country. Rivalries turned bloody as Moscow's Jewish mafia battled the Ossete vory v zakone (literally "thieves-in-law") for control of the city. Caught up in the mayhem, Yulia, only daughter of the Jewish mafia godfather, and Roman, only son of the Ossete mafia godfather, are obliged to navigate the minefield of a star-crossed love affair as they attempt to escape a destiny that appears preordained.
A Plague on Both Your Houses is the fictional story of one bloody episode in Moscow's Great Turf War, when clans fought brutally in the streets and the future of the Russian nation was anything but assured.
