The final two of our Doctor Who - Novel Adaptations range are released today, starring Peter Davison and Sylvester McCoy...

Doctor Who - Original Sin and Doctor Who - Cold Fusion are both released today, as the Doctor Who - The Novel Adaptations range concludes with two hugely popular stories, featuring the Seventh Doctor's meeting with two new companions, and the Seventh Doctor's meeting with... a younger self!

Doctor Who - Original Sin is adapted by John Dorney from Andy Lane's 1995 novel, and stars Sylvester McCoy, Lisa Bowerman, Yasmin Bannerman and Travis Oliver:

A warning from a dying alien leads the Doctor and Bernice to Earth. However Earth in this time period is not a good place to be.

The murder rate is rising, but the killers seem to be acting without motive. The TARDIS crew's investigations lead them to a military training planet, a prison inside a star, and a terrifying old foe.

And all the time they are being pursued - by two dogged Adjudicators who've stumbled onto a terrifying conspiracy. Chris Cwej and Roz Forrester.

Things will never be the same again.

Doctor Who - Cold Fusion is adapted by Lance Parkin from his own 1996 novel bringing together the Seventh and Five Doctors and a TARDIS full of companions, starring Peter Davison, Janet Fielding, Sarah Sutton, Matthew Waterhouse, Sylvester McCoy, Yasmin Bannerman and Travis Oliver:

A newly regenerated Fifth Doctor arrives on an occupied ice planet – where the Seventh Doctor is investigating dangerous energy experiments conducted by the Earth Empire. But events spin out of control when a refugee from the distant past arrives - Patience, the Doctor's Wife!

Doctor Who - Original Sin is available on Download for £12.99 and £14.99 on CD, while the three-disc Doctor Who - Cold Fusion is £14.99 and £16.99 respectively (though see below regarding the CD version).
