In a faraway country where swallows go to winter when it's cold here, once upon a time there was a king who had eleven sons and a little girl named Elisa. The eleven brothers who were princes went to school with their sabers by their side and their breasts covered with beautiful medals. They wrote with a diamond stylus on a golden blackboard and could read very well both silently and loudly. It was immediately clear that they were true princes. Elisa, the sister, had a stool made of crystal mirrors to sit down and owned an illustrated book that had cost half the realm. A little girl saves her eleven brothers from the spell thrown by a bad witch: it always happens, in fairy tales. What makes the wild swans so extraordinary are the magical pen of Hans Christian Andersen, the masterful translation of Mary Jacob and the delicate and powerful illustrations of Joanna Concejo, which reflect the strength and determination of little Elisa.
