The Tardis lands on Phobos, moon of Mars, where extreme sports nuts of the future indulge their passion for gravity boarding and wormhole jumping.

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 has always admired the work of William Shakespeare. So he is a little surprised that Charley doesn't hold the galaxy's greatest playwright in the same esteem. In fact she's never heard of him. Which the Doctor thinks is quite improbable. General Mariah Learman, ruling Britain after the Eurowars, is one of Shakespeare's greatest admirers, and is convinced her time machine will enable her to see the plays' original performances. Which the Doctor believes is extremely unlikely.

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.

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. A divorced substitute teacher living with his cat in a house his siblings want to sell, all he wants is to open a pub downtown, if only the bank will approve his loan. 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.
