I agree. Getting feedback (and potentially proper input too) from a person of colour would be an excellent idea.
As for the perspective of a Finetimer? Yes, but you’re right about it needing to be sensitive. It IS s a rich topic to explore. One of the lovely things about the novelisations is that they can push boundaries and go to places that the TV episodes need necessarily be more cautious about. I think a novelisation could expose the unpleasant nature underlying all of Finetime much more overtly than on screen. It would be a very different novelisation, but that’s no bad thing.
Master and Broken yes, I like those a lot, but they don’t even crack top 10 Lidster for me! He’s a fantastic BF writer and has done lots of fantastic work across Who, Torchwood and Benny.
