El libro de la selva

An orphaned girl arrives at a shuttered manor and finds a walled garden nobody has entered in ten years. The full novel in Spanish, with chapters short enough to read alone.

Frances Hodgson Burnett

Mole, Rat, Badger and the reckless Toad in a set of adventures along the river. Grahame's complete book in Spanish, funny and calm in equal measure.

Kenneth Grahame

A horse tells the story of his own life across the hands of many owners, kind and cruel. Illustrated across 119 pages, and still one of the strongest arguments for treating animals well.

Anna Sewell

A shipwrecked family builds a life on a tropical island using whatever they can salvage or invent. Long but episodic, so it can be read a chapter at a time.

Johann David Wyss

Quiroga's animal stories set in the jungle, written for his own children. Fully illustrated, and the entry point to one of the great Spanish language storytellers.

Horacio Quiroga
