Something strange is killing people in The Pale of Settlement-the strip of Western Russia where the Czars let Jews live.When military hero Sergei looks up from the kid's body on the street of the captured Polish town under his charge, he's met with the most terrifying thing he's seen in years: a flea-bitten orthodox Jew who looks just like him and knows his true name.When Yankev of Vishanev-down on his luck demon hunter, once powerful kabbalist-looks into the eyes of the brother he thought dead half a lifetime, he's certain he's finally back on the path God laid out for him.When the monsters attack, when the angels speak, when something darker than human violence threatens the Jews of the town with extinction, will these two have what it takes to find their way back to being a family? Will they have what it takes to stop what's coming?
