Princess Sylvie, by Elsa Beskow
Princess Sylvie persuades her father, the king, to leave the palace gardens and walk in the woods. The king is unsure. What might be in the woods? Then Sylvie's dog Oskar runs off after a long-eared hare and Sylvie's adventures begin.
This is a delightful story for young children about exploring new places and making new friends, and about the comforts of home.
