Leo and the Octopus - Isabelle Marinov

The world was too bright for Leo. And too loud. "I must be living on the wrong planet," Leo thought. Leo struggles to make sense of the world. He doesn't understand the other children in his class, and they don't seem to understand him. But then one day, Leo meets Maya. Maya is an octopus, and the more Leo learns about her, the more he thinks that perhaps he isn't alone in this world, after all..
