Doctor Who: Once and Future: A Genius for War (Special Edition)

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...

In the midst of the Time War, the Time Lords have received a communication from Falkus, the prison moon of Skaro. Its sole inmate, Davros, wishes to make them an offer. He will help them win the Time War… but only if the Doctor comes to his rescue.
