Shadows of the Apt, book 10: Seal of the Worm
Adrian Tchaikovsky2014

An ancient enemy stirs once more . . .

The Empire stands victorious over its enemies at last.

With her chief rival cast into the abyss, Empress Seda now faces the truth of what she has cost the world in order to win the war. The Seal has been shattered, and the Worm stirs towards the light for the first time in a thousand years. Already it is striking at the surface, voraciously consuming everything its questing tendrils touch.

Faced with destruction, Seda knows that only the most extreme of solutions can lock the Worm back in the dark once again. But if she will go to such appalling lengths to save the world from the Worm, then who will save the world from her?
