Karen Cushman

In medieval England, a nameless, homeless girl is taken in by a sharp-tempered midwife, and in spite of obstacles and hardship, eventually gains the three things she most wants: a full belly, a contented heart, and a place in this world.

Meggy Swann, a girl who walks with the aid of two sticks, arrives in Elizabethan London, along with her goose Louise, to stay with her father who really does not want her, and while he pursues his dream of transforming base metal into gold, Meggy undergoes a transformation herself.
