Big Finish's main Doctor Who range starts this year with The Star Men, The Contingency Club and Zaltys, as previously announced. Today we're able to confirm the story titles for much of the rest of next year.

In April, we embark on the first of three special two-disc collections of two stories, with Peter Davison as the Fifth Doctor in Doctor Who - Alien Heart by Steve Cole, and Doctor Who - Dalek Soul by Guy Adams.

Says range script editor Alan Barnes: "The double-bills in April to June came about because, er... well, we all quite liked the idea of double-bills, really! Each consists of two two-part adventures, each by a different author, one on each of the two discs; each, hopefully, has a very different style and tone to its companion piece – there should be a nice contrast between the two. First, in April, we've got the Fifth Doctor and Nyssa in Alien Heart/Dalek Soul – the first by Stephen Cole, the second by Guy Adams. Alien Heart is about a species of weird spider-like monsters linked to the systematic destruction of planets, and Dalek Soul is a particularly bleak piece set on the Dalek-occupied world of Mojoxalli."

This is followed in May by Colin Baker's Sixth Doctor starring in Doctor Who - Vortex Ice by Jonathan Morris, and Doctor Who - Cortex Fire by Ian Potter, and then in June Sylvester McCoy brings this trilogy to a close with Doctor Who - Shadow Planet by AK Benedict and Doctor Who - World Apart by Scott Handcock:

As Alan explains: "May features Lisa Greenwood as Flip – hurrah! – reunited with the Sixth Doctor, in two adventures set before her (apparent) exit in Scavenger. Vortex Ice by Jonny Morris is a brain-scrambling conundrum of a story set in a diamond mine; then Ian Potter's Cortex Fire, like its title sort-of suggests, is about an epidemic of spontaneous human combustion on a distant planet. Finally, in June, there's the return of the Seventh Doctor and Ace in Shadow Planet/World Apart. The first, by AK Benedict, has them at a far-out therapy centre, getting some very alternative medicine; then the second, by Scott Handcock, finds the TARDIS travellers marooned somewhere very inhospitable indeed."

Looking a little further into 2017, Alan comments: "Later in the year, we've got a new trilogy for Seven, Mel and Ace, including the long-awaited return of the Silurians into the Main Range; then a very special one-off adventure for the Fifth and Tegan, teamed up with another Doctor's one-time companion; and finally a full trilogy of adventures featuring the Sixth, Constance and Flip, following on from this December's Quicksilver."

July sees the award-winning John Dorney back writing for the main range with The High Price of Parking starring the Seventh Doctor, and then following a currently-unannounced title for August, we're back with the often traditional two releases in September with Matthew J Elliott's The Silurian Candidate for Sylvester McCoy's Doctor and Time in Office by Eddie Robson featuring the Fifth Doctor.

The main range can be bought individually, or subscribed to in both six- and 12-episode runs, at money-saving prices as well as special exclusives such as PDF scripts, extended extras and up to four Doctor Who - Subscriber Short Trips a year.
