He didn't believe it. But he put his his hand out again, and nothing stopped it, so he rushed forward in the pitch blackness until he hit the stone arm of the cross. And behind him, and all around him, the light began to glow again.

Only now it was different. It flickered and dimmed and struggled, like something fighting not to die. Like something else....

Like the sunballs. Like the light in the sky that meant life to a world. Flickering and feeble like an old man's heart, the last frightened wing-beats of a dying bird....

A terror took Ciaran by the throat and stopped the breath in it, and turned his body colder than a corpse. He watched....

The light glowed and pulsed, and grew stronger. Presently he was walled in by it, but it seemed fainter than before.

A terrible feeling of urgency came over Ciaran, a need for haste. The words of the androids came back to him: Failing, as we judged. If we finish in time. If we don't, none of it matters.

A shadow across the world, a darkness and a dying. Mouse slaving with empty eyes to build a shining monster that would harness the world to the wills of non-human brains.

It didn't make sense, but it meant something. Something deadly important. And the key to the whole mad jumble was here—a dark-haired boy dreaming on a stone cross.

Ciaran moved closer. He saw then that the boy had stirred, very slightly, and that his face was troubled. It was as though the dimming of the light had disturbed him. Then he sighed and smiled again, nestling his head deeper into the bend of his arm.
