Amber is in trouble. Her sister is dying—and so is her homeland. The Lifeforce stones that power their world are waning, and no one knows why. When the rulers of the land prepare a scientific expedition to study the place where the veins of the Lifeforce run deep, Amber is forced to travel as a servant with the expedition. Though Amber has longed for adventure, her dream always included her sister. Now her only wish is to return home with a cure before it’s too late.
Crops are wilting, food is scarce, and sandstorms, avalanches, and earthquakes threaten to doom the expedition. Besides this, there are more sinister forces at work. Quiet arguments and missing supplies lead Amber to believe their efforts are being sabotaged. She uncovers clues, but the real source of their trouble—and hope—lies in places she never expected.
