Colin Baker and Nicola Bryant star as the Sixth Doctor and Peri in the third instalment of the on-going Rutans vs Sontarans saga.

If you’ve enjoyed our coverage of the making of this series (which you can read more about on page 24 of this month’s issue), then this is well worth checking out. Lizzie Hopley, who among her many Big Finish credits, previously wrote for the Sixth Doctor in 2021’s The Eleven, contributes the penultimate chapter, which features a moon in the grip of a full-scale Rutan invasion.

As the Doctor and Peri attempt to help the lone Rutan Melmoth, another Doctor is at work close by – with far-reaching plans of his own.

Grave Moon can be pre-ordered from bigfinish.com (£13.99 for CD and download, £8.99 for download only), but we have FIVE copies on offer. Just send us the answer to the question below to be in with a chance of winning.
