The tenth day of Big Finishmas takes us back to the first TARDIS crew for an early four-part Doctor Who adventure...

Starring William Russell and Carole Ann Ford, Doctor Who - The Early Adventures: Domain of the Voord is the latest £2.99 Download offer in our 12 Days of Big Finish-mas run of offers:

The Doctor, Susan, Ian and Barbara land on the planet Hydra, where Admiral Jonas Kaan leads a vast flotilla of ships trying to elude the vicious race that has invaded and occupied their world. But his ships are being picked off one by one, vessels and crews dragged underwater by an unseen foe.

The time travellers find themselves pitched into battle against the Voord, the ruthless enemy they last encountered on the planet Marinus. As they take the fight to the very heart of the territory now controlled by the Voord the stakes get higher. First they lose the TARDIS... then they lose that which they hold most dear. And that's only the start of their troubles.

In the capital, Predora City, they will learn the truth of what it means to be a Voord. And that truth is horrifying.

For the next 48 hours (ending at mid-day UK time on 5th January), Doctor Who - The Early Adventures: Domain of the Voord is available for £2.99 on Download. Check out the entire Doctor Who - The Early Adventures range, including bundles on all three series, from Domain of the Voord through to last month's The Sontarans!

Don't forget that at the end of today - UK time - the special bundle price for our recently-announced six HG Wells 2017 releases goes up to the normal bundle price...
