20. Shining Darkness

For Donna Noble, the Andromeda galaxy is a long, long way from home. But even two and a half milloin light years from Earth, dander lurks around every corner...

A visit to an art gallery turns into a race across space to uncover the secret behind a shadowy organisation. From the desert world of Karris to the interplanetery scrapyard of junk, the Doctor and Donna discover that appearances can be deceptive, that enemies are lurking around every corner — and that the centuries-long peace between humans and machines may be about to come to an end.

Because waiting in the wings to bring chaos to the galaxy is the cult of Shining Darkness.

This title features the Doctor and Donna as played by David Tennant and Catherine Tate in the hit series from BBC Television.
