Shakedown - the Novel

'The Sontarans can never defeat us. It is we who will win.'

For thousands of years the Sontarans clone-warriors and the Rutan gestalt have fought each other across the galaxy. Now the Sontarans have a plan to strike at the heart of the Rutan Empire, and utterly defeat the Rutan race.

The Doctor has his suspicions, but only one Rutan spy knows the Sontarans' secret. He is being puruesd from planet to planet by Cwel and Forrester and by a Sontaran hit-squad. After a confrontation aboard the racing space-yacht Tiger Moth, the chase culminates on the library planet Sentorion - where Professor Bernice Summerfield's researches into the Sontaran/Rutan war turn into explosive reality.
