Peter Polo has been waiting his whole life for this: The Great Khan has sent him on a dangerous quest to the far-off valley of Hunza. Peter finally has a chance to step out of his famous brother's shadow and into the light of his own adventure. But the path to greatness is treacherous. Someone (or something) is causing the sacred snow leopards to disappear, and the people of Hunza fear the return of a legendary monster known as the Snow Beast. It's going to take great courage for Peter and his friends to uncover the truth and save the people of Hunza . . . before it's too late.
