The Wheel of Ice by Stephen Baxter is set during Jamie and Zoe-era Doctor Who (BBC Books £7.99 – out on 1 August):
“The Wheel: A ring of ice and steel turning around a moon of Saturn, and home to a mining colony supplying a resource-hungry Earth. It’s a bad place to grow up.
The colony has been plagued by problems. Maybe it’s just gremlins, just bad luck. But the equipment failures and thefts of resources have been increasing, and there have been stories among the children of mysterious creatures glimpsed aboard the Wheel. Many of the younger workers refuse to go down the warren-like mines anymore. And then sixteen-year-old Phee Laws, surfing Saturn’s rings, saves an enigmatic blue box from destruction.
Aboard the Wheel, the Doctor, Jamie and Zoe find a critical situation – and they are suspected by some as the source of the sabotage. They soon find themselves caught in a mystery that goes right back to the creation of the solar system. A mystery that could kill them all."
Meanwhile, Dark Horizons by Jenny T Colgan features the Matt Smith Doctor (BBC Books £7.99 – available this week):
"On a windswept northern shore, the islanders believe the worst they have to fear is a Viking attack. Then the burning comes. Water will not stop it. It consumes everything in its path - yet the burned still speak.The Doctor 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. The islanders must take on a ruthless alien force in a world without technology; but at least they have the Doctor on their side... Don't they?”
