Momo has always wanted a Lhasa terrier - a dog like the ones the
Buddhist priests hold sacred in their temples. And when a trader brings
Pempa to her parents' tea house, Momo's dream comes true. Then it is
shattered. A band of robbers steals the valuable dog, and quickly
escapes with him into the mountains. Momo is determined to catch them
and recover her beloved Pempa, but to do that she must follow the Great
Trade Route across the mountains - a path that most people avoid, and
which will surely put her life at risk.
