"The year is 1881. Seven-year-old Jinhua is left an orphan, alone and unprotected after her mandarin father's summary execution for the crime of speaking the truth.

Yet it is Jinhua who accompanies him--as Emissary to the foreign devil nations of Prussia, Austro-Hungary, and Russia--on an exotic journey to Vienna"--Amazon.com.
