La noche de los batracios

The carnival is about to start.  All human beings have been invited - everyone including Ana, who tries to catch up on sleep while she prevents her mother from floating out of a window. Islands with twin sisters, an indomitable bath, ghosts capable of drinking an entire ocean, a friendship and an out of tune choir of amphibians. Each of them has a place in this story.  Anything can happen on the night of the batrachians, but the secret is to always pay attention to who comes to dinner.
