Here is the new hardcover novel to be released this July 7th in the UK. It features the 11th Doctor and appears to be taking place during the time of Vikings and is penned by Jenny (JT) Colgan.
Here is a blurb about what the book is all about.
"Now, you may or may not have noticed, but we appear to be on fire..."
On a windswept Northern shore, at the very tip of what will one day become Scotland, the islanders believe the worst they have to fear is a Viking attack. Then the burning comes. They cannot run from it. Water will not stop it. It consumes everything in its path - yet the burned still speak.
The Doctor is just looking for a game on the famous Lewis chess set. Instead he encounters a people under attack from a power they cannot possibly understand. They have no weapons, no strategy and no protection against a fire sent to engulf them all.
Add in some marauding Vikings with very bad timing, a kidnapped princess with a secret of her own and a TARDIS that seems to have developed an inexplicable fear of water, and they all have a battle on their hands. The islanders must take on a ruthless alien force in a world without technology; without communications; without tea that isn't made out of bark. Still at least they have the Doctor on their side... Don't they?
A thrilling new adventure starring the Doctor, as played by Matt Smith.
