Big Finish are delighted to announce that hot on the heels of her appearance in this Christmas' Doctor Who Special The Husbands of River Song, the time-travelling archeologist will be back in action earlier than expected! The Diary of River Song: Series 1 will be digitally released on Boxing Day (or 26th December for those unfamiliar with British traditions)!

Alex Kingston makes her Big Finish debut in her spin-off series! The collection of four new stories will see River confront an ancient Egyptian curse, enjoy a marvellous party on a very exclusive space-station, tackle the threat of the world-ending SporeShips, and make a date with her future husband, the Eighth Doctor (Paul McGann).

Enjoy the first glimpse of this fabulous new box-set with our trailer below:

Guest stars in the new series include Alexander Vlahos as Bertie Potts, Alexander Siddig as Marcus Gifford, Imogen Stubbs as Isabella Clerkwell and Samuel West as the mysterious Mr Song. The stories have been written by Jenny T Colgan, Justin Richards, James Goss and Matt Fitton and directed by Ken Bentley.

The Diary of River Song: Series 1 can be pre-ordered today for just £20 on both CD or download from the Big Finish website. The title will be available to download on Boxing Day 2015, followed by physical copies being dispatched from our warehouse from January 8th 2016. The pre-order offer of free UK delivery stays in effect throughout, allowing you to enjoy this new series at a bargain price!

The set is also available as part of our New Series Bundle, which contains fellow January 2016 release Doctor Who: The Churchill Years Volume 1 and the July 2016 boxset Doctor Who: Classic Doctors, New Monsters Volume 1. And remember, when you choose to buy these releases on CD directly from Big Finish, you will also unlock instant access to a digital copy for download. River's first Big Finish adventure can be exclusively ordered through our website until March next year when it goes on general release.

River will return to Big Finish in Doctor Who: Doom Coalition 2, accompanying the Eighth Doctor (Paul McGann), Liv Chenka (Nicola Walker) and Helen Sinclair (Hattie Morahan) in their next battle with the Eleven (Mark Bonnar). Click here for more details.

And don't forget - River Song joins the Twelfth Doctor (Peter Capaldi) on our screens this Christmas Day at 5.15pm in The Husbands of River Song. Check out the trailer below!
