Growing up in Soviet Russia, Kat Knopman worships her parents, temperamental Anechka and soft-hearted, absent-minded Misha. Young Jewish intellectuals, they teach literature at a Moscow school, run a drama club, and dabble in political radicalism. Kat sees herself as their heir and ally. But when she's diagnosed with rapidly-progressing scoliosis, the trajectory of her life changes, and she finds herself at a different institution--a school-sanatorium for children with spinal ailments. Confined to a brace, surrounded by unsympathetic peers, Kat embarks on a quest to prove that she can be as exceptional as her parents.
