Unfinished Corner

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.
