Second paragraph of third story (“The Myriapod Mutiny”, by Emma Norry):

When the Great Freeze descended, they buried themselves deeper still and made a pact – to ensure, above all else, their mutual survival. Come what may. Yet neither foresaw the Great Collision which obliterated not only their planet, but their plans for survival too …

An anthology of eleven short stories about Doctor Who characters before their first appearances on TV Doctor Who. No editor’s name is given, but I am assuming it was Dave Rudden because three of the stories are by him (featuring Kate Stewart, Castra and Jenny, and the Master/Missy); whoever did edit it, it is a shame that they are not given credit.

Two of the other stories are by the actors who actually played the respective companions on screen – Sophie Aldred (Ace) and Katy Manning (Jo Grant), both rather interesting takes on their own characters’ back-stories, Sophie Aldred’s being a good start to the collection as a whole (and available here).

Five of the other six are by women of colour who haven’t previously written for the Whoniverse but have strong writing credentials elsewhere – oh, OK, I’ll name them: Emma Norry (Yaz and Ryan meet the Second Doctor); Temi Oh (Davros); Faridah Àbíké-Íyímídé (Martha Jones meets the Ninth Doctor); Nikita Gill (Amy and Rory as kids); and Jasbinder Bilan (Clara pre-meets the Eleventh Doctor). The other is by Mark Griffiths (Sarah Jane Smith meeting the Fourth Doctor as a schoolgirl). One of them is not very good, but the rest are all excellent, and I can recommend this to anyone with a vague awareness of the series. You can get it here.
