What’s it about?

The story.

Gigantic is the smallest blue whale in the whole Atlantic. While his big brother Titan is admired for being the biggest and best, little Gigantic keeps himself to himself, making new friends among the ocean's tiniest creatures and perfecting his somersaults and flips. But being small can feel lonely when everyone celebrates being big. Then disaster strikes: Titan becomes stranded on the sand, and it is only Gigantic and his gang of little sea-creature friends who can save him. Can the smallest whale in the Atlantic prove that it's possible to be tiny and tough all at once? Told in Rob Biddulph's warm, bouncing rhyme and packed with his glorious, colour-drenched ocean artwork, Gigantic is a joyful, reassuring adventure for anyone who has ever felt overlooked for being small. Created in partnership with Whale and Dolphin Conservation, it slips a gentle love of the sea and its creatures into a big-hearted, feel-good story.
