''Once, not long ago, and in a place not far from here, a baby girl was born. Eva. In that same moment, in a place far away on the other side of the world, an egg cracked. The tip of a tiny beak poked through, and a curlew chick was born. Sister Chick.'

'Eva dreams of places far beyond her own backyard. While other kids go by, fooling around with their friends, Eva is watching, listening for the call of a curlew flying high overhead; waiting for the bird with the long slender beak. And when the curlew finally arrives, Eva goes on a magical journey, flying with Sister Chick from the distant marshlands of Siberia to the ancient southern land of Australia.'
