The way back

A historical fantasy that follows Eastern European teens Yehuda and Bluma on a journey through the Far Country, the Jewish land of the dead.
For the people of Tupik, a tiny village in Eastern Europe, demons are everywhere: dancing on the rooftops in the darkness of midnight, congregating in the trees, even reaching out to try and steal away the living. The demons have a land of their own: a Far Country, governed by demonic lords and ladies. When the Angel of Death comes strolling through the little shtetl of Tupik one night, Yehuda Leib and Blume will be sent spinning off on a journey through the Far Country. There they will make pacts with ancient demons, declare war on Death himself, and maybe-- just maybe-- find a way to make it back alive. -- adapted from jacket
