A faraway land.

The son of a wealthy businessman.

And the adventure of a lifetime.

In Mongolia, the inhabitants of a remote village have suffered the theft of their most prized possession—a beautiful moonstone.

Their village sits atop one of the biggest mineral deposits in the world, and foreign mining companies know it. Enter...

AINSLEY WALKER

Assigned to find the gemstone, she embarks on an epic journey across the open grasslands of Mongolia, home to one of the biggest empires in history.

Running from the ruins of Buddhist monasteries to abandoned Soviet military bases—

—from the peaks of the Altai Mountains to the vast plains of the Gobi Desert—

Ainsley can't stop until she's finished the job, even if it means pushing herself to the very limits of her physical endurance.

Will she find the villagers' moonstone before it's too late?
