David is the small boy who is always asking questions. Simon and Inés take care of him in their new town Estrella. He is learning the language; he has begun to make friends. He has the big dog Bolívar to watch over him. But he'll be seven soon and he should be at school. And so, David is enrolled in the Academy of Dance. It's here, in his new golden dancing slippers, that he learns how to call down the numbers from the sky. But it's here too that he will make troubling discoveries about what grown-ups are capable of.
