What’s it about?
The story.
When a tiny whale calf is born, his mother lifts him to the surface to take his first breath. She stays close as he grows, guiding him and keeping him safe, until he is strong enough to swim at her side, and together they set off on a great journey across the oceans. One day the time will come for the grown calf to strike out alone, but wherever he goes and whatever he becomes, his mother will be there, sending her song of love across the deep. Stephen Hogtun's second picture book, following his acclaimed debut Leaves, is filled with luminous, layered blues and a spare, tender text. It tells a universal story about the love between a parent and child and the way that love holds even when children grow up and swim away. Reassuring and beautiful in equal measure, it is a perfect bedtime book for the very young and a moving read-aloud for the grown-ups sharing it, ideal for cuddling up close.
