For the Cybermen have journeyed back in time to prevent the destruction of their home world. And for Mondas to survive, the Earth must die.

Toby Longworth reads this original adventure for the Thirteenth Doctor and Graham, as played on TV by Jodie Whittaker and Bradley Walsh. It's 1970, and record-breaking explorer Silvia Sandstrom has completed an epic lone drive to the North Pole. But as she activates her on-board experimental equipment, her vehicle is swallowed by a massive hole in the ice. Meanwhile the TARDIS is drawn to an arid wasteland, also apparently at the North Pole. There the Doctor and Graham meet Silvia - but it's clear that she is a woman out of her own time.

A visit to the Grand Canyon begins with disaster for the Doctor and Peri, when the TARDIS plunges into a ravine. The travellers' only hope is to descend to the valley on foot and then track the course of the Colorado river. Their perilous journey is fraught with danger, even before they encounter a band of 19th Century explorers led by Major John Wesley Powell. Joining the watery expedition, the Doctor and Peri begin to despair of ever seeing the TARDIS again. As food supplies dwindle, so do the group's options. This is a journey which some of them will never return.

On the serene planet Deva Loka, an expeditionary force from Earth is dangerously out of control. It's not only the peaceful race of the Kinda who are at risk. A gentle stroll in the lush jungle leads the Doctor and Adric to an unexpected confrontation - and puts them at the mercy of a maniac. But it is Tegan, lulled to sleep by mysterious wind-chimes, who comes closest to a danger than threatens not only her sanity but the existence of the whole planet.

For the Tenth Doctor, the festive season always brought adventure. In fact, he's saved Christmas across space and time more times than we ever knew.

Because even in the jolliest of seasons there's a world or two to save.

An Escape Room with a sting in its tail is the setting for the Doctor and Jo's latest encounter with a familiar enemy. Three young graduates and their tutor race against time to crack the codes, open the exit door, and obtain 'A New Life' - at least, that's what the publicity said. As the Doctor observes proceedings, he forms a growing suspicion that something far more sinister lurks on the other side of the door. What's worse, the room appears set to eliminate anyone who doesn't make the grade.

The hugely powerful Key to Time has been split into six segments, all of which have been disguised and hidden throughout time and space. Now the even more powerful White Guardian wants the Doctor to find the pieces. With the first segment successfully retrieved, the Doctor, Romana and K9 trace the second segment of the Key to the planet Calufrax. But when they arrive at exactly the right point in space, they find themselves on exactly the wrong planet - Zanak.

The waters of the Pacific Ocean form the backdrop of this foray into Eighteenth Century seafaring for the Doctor and Martha, when the TARDIS materialises on board the Blue Groper sailing ship. Grudgingly accepted as stowaways by Captain Sadler's crew, the travellers learn that the ship is on a mission to Luna Puesta, 'the land where the moon has set'. There, just off the coast of New Zealand, Professor James Tomlinson hopes to locate a missing archaeological link between dinosaurs and man.
