Esquivel is a rat that seeks by all means to escape what appears to be the inevitable destiny of his species: the rateria, and undertakes a tireless search for his sisters, white rats that disappear without leaving the slightest trace. In his journey through the sewers of the underworld in which he lives, he will meet characters such as Rafia and Ratatatá, who will eventually lead him to the delirious domains of Dr. Plasma, a radioactive rat specialized in creating short circuits, or trying to decipher the riddles of the Great Mole, a being that feeds on salty worms, whose secrets will offer hope to fulfill its mission. While gnawing olive bones at the Paraís bar, Esquivel wonders if he is condemned to live forever in the paradise of rats, "a dump where everyone wants to make the most of the others."

The paradise of the rats is a funny little fable written by Luigi Amara, masterfully illustrated by Trino, where through the misadventures of Esquivel, a rat who tries by all means to conduct himself in a different way, the story shows the corrosive effect of Corruption at all levels. And it is that as this book makes clear, far from being an issue that only occurs in the dome of societies, corruption is a way of life that destroys the social fabric and ruins the possibility of life in common.
