A Cartographic Analysis of the Dream State — Pat Murphy

Traveling across the Martian polar cap, the second TransPolar Expedition is tracing the shape of the hidden lands beneath the ice and snow. Sita, the expedition's cartographer, has a talent for interpreting the shades and squiggles that the computer produces from satellite photos and sonic recordings. She takes ambiguous data and makes a clear and precise map of lands no one has ever seen.

But Sita knows that maps are black-and-white portraits of a world that exists in shades of gray and, like cartographers before her, she knows that dragons lurk beyond the edges of every map. At night, in the darkness of her dreams, she believes in the yeti, the messengers from the secret lands, the dark-eyed dream beasts that haunt the crevasses and move as softly as the blowing snow.

The world is not all that it seems on the surface. Beneath the polar ice lies danger and discovery.
