The Hands of the Emperor - Victoria Goddard

An impulsive word can start a war.

A timely word can stop one.

A simple act of friendship can change the course of history.

Cliopher Mdang is the personal secretary of the Last Emperor of Astandalas, the Lord of Rising Stars, the Lord Magus of Zunidh, the Sun-on-Earth, the god.

He has spent more time with the Emperor of Astandalas than any other person.

He has never once touched his lord.

He has never called him by name.

He has never initiated a conversation.

One day Cliopher invites the Sun-on-Earth home to the proverbially remote Vangavaye-ve for a holiday.

The mere invitation could have seen Cliopher executed for blasphemy.

The acceptance upends the world.
