Zagreus sits inside your head. Zagreus lives among the dead. Zagreus sees you in your bed and eats you when you're sleeping....

Twas the night before Christmas, and all through the house not a creature was stirring.... But something must be stirring. Something hidden in the shadows. Something which kills the servants of an old Edwardian mansion in the most brutal and macabre manner possible. Exactly on the chiming of the hour, every hour, as the grandfather clock ticks on towards midnight. Trapped and afraid, the Doctor and Charley are forced to play detective to murders with no motive, where even the victims don't stay dead.

The year is 1989. In London, safecracker Raine Creevy breaks into a house - and finds more than the family jewels. In the Middle East, the kingdom of Sayf Udeen is being terrorised by Soviet invaders and alien monsters. And on the Scottish border, a highly guarded facility contains an advanced alien weapon. These are all part of the Doctor's masterplan. But masterplans can go awry....

October 1930. His Majesty's airship, the R101, sets off on her maiden voyage to the farthest-flung reaches of the British Empire, carrying the brightest lights of the imperial fleet. Carrying the hopes and dreams of a breathless nation. Not to mention a ruthless spy with a top-secret mission, a mysterious passenger who appears nowhere on the crew list, a would-be adventuress destined for the Singapore Hilton...and a Time Lord from the planet Gallifrey.

The Doctor and Romana find themselves in the Proxima System, where enigmatic Conglomerate CEO Cuthbert has been conducting his infamous 'experiment'. An experiment which might accidentally rip the universe apart. Meanwhile, living conditions on Proxima Major have become harsh and hostile. Climate change has turned the landscape into a freezing wasteland and an alien power has condemned much of the population to life inside internment camps.

The human race is locked in deadly combat with the android hordes in the Orion System. Light-years from the front line, the Doctor and Charley arrive to sample the dubious delights of a galactic backwater, little suspecting that the consequences of the Orion War might reach them there. But High Command's lust for victory knows no bounds.

When the Doctor and Donna visit London's Technology Museum for a glimpse into the future, things don't go to plan. The most brilliant IT brain in the country can't use her computer. More worrying, the exhibits are attacking the visitors, while outside, people seem to be losing control of the technology that runs their lives. Is it all down to simple human stupidity, or is something more sinister going on?

The web of time is stretched to breaking. History is leaking like a sieve. In the Citadel of Gallifrey, the Time Lords fear the end of everything that is, everything that was...everything that will be. The Doctor holds the Time Lords' only hope - but exactly what lengths will the Celestial Intervention Agency go to in their efforts to retrieve something important from within his TARDIS? What has caused Imperiatrix Romanadvoratrelundar to declare war on the rest of creation? And can an old nursery rhyme about a monster called Zagreus really be coming true?

The Doctor and Charley decide to take a well-deserved break from the monotony of being chased, shot at and generally suffering antisocial behaviour at the hands of others. And so they end up in Venice, well into Charley's future, as the great city prepares to sink beneath the water for the last time...which would be a momentous, if rather dispiriting, event to witness in itself.

Hurrah! The deadly Daleks are back! Yes, those loveable tinpot tyrants have another plan to invade our world. Maybe this time because they want to drill to the Earth's core. Or maybe because they just feel like it. And when those pesky pepperpots are in town, there is one thing you can be sure of. There will be nonstop, high-octane mayhem in store. And plenty of exterminations! But never fear. The Doctor is on hand to sort them out. Defender of the Earth, saviour of us all.

In his first-ever Doctor Who novel, Tom Baker’s incredible imagination is given free rein. A story so epic it was originally intended for the big screen, Scratchman is a gripping, white-knuckle thriller almost 40 years in the making. The Doctor, Harry and Sarah Jane Smith arrive at a remote Scottish island when their holiday is cut short by the appearance of strange creatures - hideous scarecrows who are preying on the local population. The islanders are living in fear, and the Doctor vows to save them all.

Ryland Grace is the sole survivor on a desperate, last-chance mission - and if he fails, humanity and the Earth itself will perish. Except that right now, he doesn't know that. He can't even remember his own name, let alone the nature of his assignment or how to complete it. All he knows is that he's been asleep for a very, very long time. And he's just been awakened to find himself millions of miles from home, with nothing but two corpses for company.

It’s 1984, and life has changed beyond recognition. Airstrip One, formerly known as Great Britain, is a place where Big Brother is always watching, and nobody can hide. Except, perhaps, for Winston Smith. Whilst working at the Ministry of Truth, rewriting history, he secretly dreams of freedom. And in a world where love and sex are forbidden, where it’s hard to distinguish between friend and foe, he meets Julia and O’Brien and vows to rebel.

Six days ago, astronaut Mark Watney became one of the first people to walk on Mars. Now, he's sure he'll be the first person to die there. After a dust storm nearly kills him and forces his crew to evacuate while thinking him dead, Mark finds himself stranded and completely alone with no way to even signal Earth that he’s alive - and even if he could get word out, his supplies would be gone long before a rescue could arrive. But Mark isn't ready to give up yet.

Inheriting your uncle's supervillain business is more complicated than you might think. Particularly when you discover who's running the place. Charlie's life is going nowhere fast.

Then his long-lost uncle Jake dies and leaves his supervillain business (complete with island volcano lair) to Charlie. But becoming a supervillain isn't all giant laser death rays and lava pits.

Jazz Bashara is a criminal. Well, sort of. Life on Artemis, the first and only city on the moon, is tough if you're not a rich tourist or an eccentric billionaire. So smuggling in the occasional harmless bit of contraband barely counts, right? Not when you've got debts to pay and your job as a porter barely covers the rent. Everything changes when Jazz sees the chance to commit the perfect crime, with a reward too lucrative to turn down.
