BBC Books will publish two novels to tie into the multi-platform Doctor Who story, Time Lord Victorious, starring the eighth, ninth and tenth Doctors.

The Knight, the Fool and The Dead and All Flesh is Grass are scheduled for release in October and December, respectively and are now available for pre-order.

The two novels are part of the epic saga Time Lord Victorious, a brand-new multi-platform Doctor Who story told across audio, novels, comics, vinyl, digital, immersive theatre, escape rooms and games.

Set within the Dark Times at the start of the universe, three incarnations of the Doctor must travel across space and time as they defend the universe from a terrible race.

The synopsis for The Knight, the Fool and The Dead by Steve Cole:

We live forever, barring accidents.

Just like everyone else in the universe. The tenth Doctor travels back to the Dark Times, an era where life flourishes and death is barely known… Then come the Kotturuh – creatures who spread through the cosmos dispensing mortality. They judge each and every species and decree its allotted time to live. For the first time, living things know the fear of ending. And they will go to any lengths to escape this grim new spectre, death.

The Doctor is an old hand at cheating death. Now, at last, he can stop it at source. He is coming for the Kotturuh, ready to change everything so that life wins from the start. Not just the last of the Time Lords. The Time Lord Victorious.

The synopsis for All Flesh is Grass by Una McCormack:

Even a Time Lord can’t change the past.

A wasteland. A dead world… No, there is a biodome rising from the ashes. Here, life teems and flourishes, with strange, lush plants and many-winged insects with bright carapaces – and one solitary sentient creature, who spends its days talking to the insects and tending this lonely garden. This is Inyit, the last of the Kotturuh.

Transported back to The Dark Times, the Tenth Doctor has sworn to stop the Kotturuh, ending death and bringing life to the universe. But his plan is unravelling – instead of bringing life, nothing has changed and all around him people are dying. Death is everywhere. Now he must confront his former selves – one in league with their greatest nemesis and the other manning a ship of the undead…

The Knight, the Fool and The Dead and All Flesh is Grass are available for pre-order now.
