Doctor Who: Caerdroia

Self-exiled to a new universe, separated from the TARDIS, opposed and manipulated by the Divergence and their agent the Kro'ka, the Eighth Doctor has been struggling to work out the nature of the cosmic game in which he's an unwilling pawn. Now, at last, he has a chance to find the answer — and regain the TARDIS!

Threatened and desperate, the Kro'ka abandons his behind-the-scenes machinations to confront the Doctor directly. But will both of them lose their way in the maze of the strange world in which they find themselves? A world in which a clock may have a cuckoo but no hands, a labyrinth imprisoning a paradox, and a Garden of Curiosities reveals something the Doctor has never seen before.

As the Doctor faces these challenges, Charley and C'rizz provide valuable help. But with the TARDIS itself at stake, the Doctor reaches deep inside himself to find some surprising new allies.
