If you like what you hear, remember, you've only got until December 31st to purchase UNIT Dominion before it reverts to its normal price. At the moment, it's still available for the bargain rate of £30 for the five-CD box set or £25 for the digital download.

The universe stands on the brink of a dimensional crisis – and the Doctor and Raine are pulled into the very epicentre of it.

Meanwhile, on Earth, UNIT scientific advisor Dr Elizabeth Klein and an incarnation of the Doctor she's never encountered before are tested to the limit by a series of bizarre, alien invasions.

Meanwhile, tomorrow, David Richardson, Paul Spragg and Nick Briggs return for four, daily, special Christmas podcasts! There will be guests galore... and some eating!

Don't forget, if you want to contribute to the podcast, you can do so by emailing [email protected]. Thanks to all of you who have written in so far this month. Paul Spragg will be reading out a selection of your emails.
