The Slitheen Excursion by Simon Guerrier

1500BC - King Actaeus and his subjects live in mortal fear of the awesome gods who have come to visit their kingdom in ancient Greece. Except the Doctor, visiting with university student June, knows they're not gods at all. They're aliens. For the aliens, it's the perfect holiday - they get to tour the sights of a primitive planet and even take part in local customs. Like gladiatorial games, or hunting down and killing humans who won't be missed. With June's enthusiastic help, the Doctor soon meets the travel agents behind this deadly package holiday company - his old enemies the Slitheen. But can he bring the Slitheen excursion to an end without endangering more lives? And how are events in ancient Greece linked to a modern-day alien plot to destroy what's left of the Parthenon? Featuring the Doctor as played by David Tennant in the hit BBC Television series.

But the battles rage on across countless solar systems. And now the future of our galaxy hangs in the balance... The Doctor finds himself stranded on board a starship near the frontline with a group of ruthless bounty hunters. Earth Command will pay them for every Dalek they kill, every eye stalk they bring back as proof.

But where the Daleks are involved, nothing is what it seems, and no one is safe. Before long the tables will be turned, and how will the Doctor survive when he becomes a prisoner of the Daleks? Featuring the Doctor as played by David Tennant in the hit BBC Television series.

A unique look into the BBC's most popular family drama, Doctor Who: The Writer's Tale is a year in the life of the hit television series, as told by the show's Head Writer and Executive Producer. A candid and in-depth correspondence between Russell T Davies and journalist Benjamin Cook, the book explores in detail Russell's work on Series Four, revealing how he plans the series and works with the show's writers; where he gets his ideas for plot, character and scene; how actors are cast and other creative decisions are made; and how he juggles the demands ofDoctor Who with the increasingly successful Torchwood and The Sarah Jane Adventures spin-offs.

Russell's scripts are discussed as they develop, and Russell and Ben's wide-ranging discussions bring in experiences from previous series ofDoctor Who as well as other shows Russell has written and created, including Queer As Folk, Bob and Rose, and The Second Coming. The reader is given total access to the show as it's created, and the writing is everything you would expect from Russell T Davies: warm, witty, insightful, and honest.

Fully illustrated with never-before-seen photos and artwork – including original drawings by Russell himself -The Writer's Tale is a not only the ultimate Doctor Who book, but a celebration of great writing and great television.
