Publisher's summary
“Find the Doctor... stop the Doctor... and, if necessary, kill the Doctor!”

Recruited by the Celestial Intervention Agency to track down his oldest enemy, finds himself thrown into a mission that will take him into deepest Dalek territory.

Abandoned on the planet Redemption, he assembles a crew and acquires a ship – the journey that follows is certain to test them all... and not everyone will survive.
