At the height of the Time War, the Doctor answers a distress call from Skaro, and finds a child where a weapon should be. She is frightened. She is broken. And she was never meant to exist.

As Dalek experiments blur the line between creation and corruption, the Doctor makes a choice that defies both the Daleks and his own people. He offers the child something no one ever has before: mercy.
But the Time War does not forgive kindness.
When the truth of the child’s purpose is revealed, the Doctor is forced to confront an impossible reality – one where compassion becomes the weapon used against him, and saving one life may doom all others. Trapped between the Daleks, the Time Lords, and a universe tearing itself apart, the Doctor faces the moment that will redefine him forever.
This is the story of the choice that breaks the Doctor. The lie he tells himself. And the day he stops being the Doctor at all.
The Doctor and the Child is the final chapter in . . .
The Time Traveller’s Tales.
