High in the foothills of the Himalayas, a young Nepalese boy, Lhakpa, and his four loyal yaks - Yak, Nak, Zopchok and Zum - embark on a perilous journey to find the mythical castle, Shangri-La. On this daring adventure Lhakpa and his yaks battle the perils of the misty mountains - freezing snowstorms and danger prowling in the shadows. And watching from the snow-covered peaks above is their greatest challenge of all - the legendary Yeti . . . Written by mountaineer Peter Hillary and illustrated by award-winning artist Ant Sang, this fable of perseverance and the realisation that not everything in life is as it seems is a wonderful read for adventurers of all ages.
