Yelp! Yeti! Everest Ever After

When Dev's boredom lands him in some trouble, his parents banish him to Everest Base Camp for the summer to join his dad on a research trip. With freezing winds, endless maths worksheets and ice instead of ice cream, Dev expects to have a miserable time. But when he reunites with his friend Hiu the Yeti, he's invited to Yetiville, which is plagued by a horrible smell. How did the stench reach the world's highest mountain? And can Dev help the Yetis clear it away while defeating boredom once and for all?
