‘Oh I think it just might be.’ The Doctor paused for a moment. She hopped from foot to foot. Ryan knew this dance too. It was the do we run away from this or towards it dance. And he knew exactly which she’d choose. ‘Come on, let’s take a little look. There’s only two things I don’t believe in, and one’s coincidence.’
Apparently the first published of the three recent Thirteenth Doctor books, by Juno Dawson (possibly the first out trans writer to contribute to the official Whoniverse; she also did a couple of Torchwood audios for Big Finish in 2017). It's really rather good - the story starts at the end of an adventure, following which the Doctor and friends return to the same planet centuries later, to discover that their first visit has become the founding myth of the dominant oppressive religious cult, with Graham remembered as the Doctor, the Doctor herself largely forgotten, and their own past used to justify slavery. It is very well done and packs a lot of action and thought into 227 pages. Recommended. You can get it here.
