A message book, but not too heavy. And the message is wildly needed: before punishing, before banishment, try to figure out what is stressing someone out. The witch inherits a four-footed, troublesome table. But with a bare minimum of observation, the witch notices that the table is cold, naked, lonely, and tired. Not to spoil the big reveal, but she takes care of the table's needs and everyone's life is better for it.
A lesson for everyone, and yet another reason why picture books aren't just for kids.
