Cover blurb
Gallifrey is in a state of crisis, facing destruction at the hands of an overwhelming enemy. And the Doctor is involved in three different incarnations - each caught up in a deadly adventure, scattered across time and space. The web of time is threatened - and someone wants the Doctor dead.

The three incarnations of the Doctor must join together to set time back on the right track - but in doing so, will they unleash a still greater threat?

The Seventh Doctor is in Episode 1 of this four-part story; the Fifth Doctor is in episode 2; the Sixth Doctor is in episode 3; and all three Doctors are in the final episode.
