The 6th Doctor and Peri are back in an all-new adventure!

The TARDIS drifts into a dying space station where silence has become a force of nature.
For the Sixth Doctor and Peri, the Atrium is more than a resonance hub. It’s a lock. A faultline between universes. And something has found it.
They are the Vesperkind—entities who feed on resonance, starvation made manifest, following the echo of a mistake the Doctor once made. A breach opened as a release valve has become a thread they can cross, and now the universe has gone quiet enough for them to return.
Trapped between collapsing realities, the Doctor must turn sound against silence, link the station to the distant TARDIS, and seal the breach without destroying everything tethered to it. If he fails, the universe won’t fall into war . . .
It will fall into quiet.
A quiet no one comes back from.
