Colgan commented: “Writing Dark Horizons has been, as my friends and family already know, a dream come true for me. I grew up on Terrance Dicks and I’m beyond thrilled to be joining the ranks of Doctor Who novelists.”

Albert De Petrillo, Senior Editorial Director at BBC Books, added: “We were deeply impressed with the originality and enthusiasm [that Colgan] brought to the task of writing an 11th Doctor adventure. Dark Horizons is simply a terrific Doctor Who story – fast-paced, thrilling and often quite funny, it captures Matt Smith’s Doctor perfectly and introduces some very memorable new characters as well.”

The official synopsis is as follows: “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?”
