Will a Pied Piper save the city's children from the "rats" that plague it? La tortuga de Darwin tells the story of Harriet, the tortoise that Charles Darwin brought back to England from the Galapagos. Since her voyage, Harriet has evolved into a turtle-woman, able to think, speak, and bear witness to the terrible events of the past two centuries.
