Jewish mythology has it that when God created the universe, one corner of it was left unfinished. Opinion is divided on why, but everyone agrees that the Unfinished Corner is a dangerous place full of monsters. Twelve-year-old Miriam neither knows nor cares about the Unfinished Corner. She's too busy preparing for her Bat Mitzvah, wrestling with whether she even wants to be Jewish--until a peculiar angel appears, whisking her, her two best friends, and her worst frenemy off to this monstrous land with one mission: finish the Unfinished Corner.
