Prose Some Doctor Who stories, especially about the Eighth Doctor, which are just so weird that you can't quite believe what you've just read. Part of an anthology of stories all set in the capital of the Czech Republic (which in and of itself is an interesting choice - did someone at Big Finish have a stake in their tourism?) this follows Yan, a local artist who saves the life of a amnesiac young woman who becomes his muse and changes his career fortune before the actual reality of his situation revealed to him.
Stop here if you want avoid spoilers.
Gone? No? On your head. What we discover is that the city is actually a reproduction produced by aliens a trillion years in the future as part of an exhibition in a space which probably resembles the tesseract in Interstellar. This futuristic version of Prague only exists in a snow globe and Yan and the rest of the citizens are echoes of real people in the distant past and that the Doctor accidentally dropped Charley in the middle of that which is how she lost her memory. She's the girl.
Here's where it gets tricky. Yan isn't keen to give her up. So he all but keeps her prisoner in his house and they have a relationship and so now we discover that some time late in the second season of her audio adventures with the Doctor, Charley spent nearly a year in sharing a bed with a gaslighting failed artist, only remembering fragments of her life in the TARDIS. Then off she pops into another adventure and it's never mentioned again. Like I said, some Doctor Who stories are weird.
Placement: Throughout the story its revealed that Yan is creating artworks based on her memories of earlier audio stories. The latest mentioned is Face of Grail so I'm going to put this between Seasons of Fear and Embrace the Darkness. After that the story arc asserts itself and things get messy.
