A breathtaking picture book about incredible animal migrations, illustrated by the winner of the 2019 Waterstones Children's Book Prize, Jenny Lovlie. Over the cold, mirrored waters of the Arctic, a tiny tern sets off on the world's longest animal migration. On her way, she passes humpback whales, caribou, Canada geese, leatherback turtles and monarch butterflies, each on their own incredible journey south for winter. When the Arctic tern finally arrives, she must find a new home on the Antarctic shore . . . until it's time to return to the northern skies once again. A beautiful, lyrical and reassuring bedtime story, perfect for young animal lovers, with a map and double-page spread of non-fiction facts at the end.
