The Abominables- Eva Ibbotson

Deep in the Himalayas, the daughter of an English earl is kidnapped by a huge hairy monster. Agatha Farlingham is introduced to a family of motherless yetis and devotes her life to their upbringing. She teaches them to talk, tells them stories and insists on polite manners. But as time passes, tourists and yeti-hunters arrive in to the mountains. Agatha knows that there is one place where they would be protected – at her home in England.

So begins a hugely entertaining road trip half way across the world…
