Thrown off course by a howling storm, the TARDIS lands in a bleak, desolate stretch of countryside. The Doctor deduces that it has arrived in Hampshire in the 1920s and, sniffing the air, he smells a distinct odour of sulphur - indicating that a spaceship has crashed in the area. While Rory goes to fetch an umbrella, Amy and the Doctor brave the rain to find the stricken craft. It is huge, shiny, silvery-blue - and completely empty. A set of footprints leads to a cosy-looking, old-fashioned cottage: but the house, too, is deserted.

This is an exclusive, original adventure for the 10th Doctor, read by David Tennant. Featuring additional music and effects, Doctor Who: Dead Air has never been previously published. Hot on the heels of a creature that exists through sound, the Doctor lands on a pirate radio station boat in the late 1960s. The creature has already killed some of the DJs, and the Doctor befriends the survivors. But then the lights go out, and a desperate race for survival begins.

When the TARDIS lands on Orkney in the near future, the Doctor and Amy arrive to find a large demonstration in progress over the construction of new electricity pylons. The Doctor tries to break things up peacefully – but suddenly the road splits open without warning and swallows police, security guards and protestors alike. Separated from the Doctor, Amy takes charge of transporting the wounded to hospital – but the rescue mission becomes a terrifying ride....

The TARDIS touches down on Nadurniss, a planet under quarantine. A joint Nadurni/human mission has recently landed on the planet to survey it for possible re-colonisation. Two millennia have passed since the Nadurni Empire fell at the end of the Prokarian War, and Nadurniss seems to be a lifeless, barren world - but a mysterious illness is infecting the Nadurni, and now the whole team is in danger.

The Doctor, Amy, and Rory are awe-struck by their first sight of Hope Eternal, a super-earth bigger than Earth itself with heavy gravity, volcanoes, and a crust loaded with mineral deposits. But their wonder is cut short when they discover a body dumped on the ground - a huge figure with extraordinarily long arms covered in thick, purple scales. Yet the corpse is not alien: he's human, albeit unlike any human Amy and Rory have ever seen.
