Publisher's summary
The Time War. The Doctor has been injured and brought to a Time Lord field hospital. His body glows with energy, but this is no regeneration into a future form – instead, the Doctor’s past faces begin to appear as he flits haphazardly between incarnations…

Staggering to his TARDIS, the Doctor sets out to solve the mystery of his ‘degeneration’. Who has done this to him? How? And why? From the Earth to the stars, across an array of familiar times and places, he follows clues to retrace his steps, encountering old friends and enemies along the way. Tumbling through his lives, the Doctor must stop his degeneration before he loses himself completely...

Slipping between bodies, the Ninth Doctor finds his TARDIS caught between universes as the cosmos starts to break down. A Doctor from another reality arrives and they join forces with Liv Chenka and the Lumiat to find the cause. Someone has desecrated the mythical Hall of the Time Lord Immemorial, where the sands of time from the multiverse are held. And those sands are running out…
