Pema lives in the shadow of the Walking Mountain, and for as long as he's known the mountain has been moving north. Singay is a young member of the White Sisters, an order of priestesses worshipping the way of the mountain. For both, their idyllic existence is about to be turned upside down. After hundreds of years, it looks like the mountain has started walking backwards. Pema and Singay find themselves in a race against time, hurled into an epic adventure across a continent of wonders.
