International Yeti Collective: Shadowspring (the)

The International Yeti Collective: Shadowspring by Paul Mason (Illustrated by Katy Riddell)
Henry, the new boy at a crumbling boarding school in the Scottish Highlands, never believed the rumours of yeti roaming the misty hills — until he gets lost in the forest and meets Tadpole, a young yeti from the hidden world of Shadowspring. But the precious spring water that keeps her community alive is vanishing, and danger is closing in. When Tadpole accidentally reveals their secret to Henry, the unlikely pair must work together to save her home. A heartwarming, action-packed adventure of friendship, courage, and environmental hope — perfect for fans of Abi Elphinstone, The Polar Bear Explorers’ Club, and Frostheart.
