Imagine. You're a bird, only fifteen inches long. You spend half the year on one side of the planet and then you fly to the other side for the rest. Round trip: eighteen thousand miles. On the way there you touch down in many different countries; you're just a passing visitor. And on the way back . . . there is nowhere to stop. Just ocean for seven thousand miles.

A story about two true fantastical flights; that of the godwits around and across the Pacific and a woman's emigration from Croatia to New Zealand.

A young girl and her grandmother, Baba Didi, are on a beach watching the godwits preparing to migrate. Talking about the birds's courageous journey across the Pacific resonates with generations of human migration, from the Maori reaching New Zealand to Baba Didi's journey from Croatia.

Illustrated with warmth and radiance this is an epic story told with charm. A tale of the resilience it takes "just to get there" when the going is rough and the road is long.
