Well this proved a pretty decent, but very clumsily-made, drama. When a teenaged Frida Kahlo sees a lot of swimey things in the air above her local park, the female Doctor turns up to decide they're living code entities, and in searching for experience that human biological forms might give them, could see to the end of the planet. Saving the day will require imagination, and some pain – but between them, the two women have more than enough – or do they?
So what's clumsy about it? Well, Frida knowing about the chupacabra decades before it was first reported is amateurish. The way the bilinguality – you know, the easy phrases the author knows in Spanish and English appearing in both, just to add 'flavour' – survived after the TARDIS Translator was switched on makes no sense. A defensively-positioned cupboard seems to disappear. And when the binary code/binary pronouns woo-woo turns up as a joke?/device?, you see the issues Doctor Who has faced for many a year, writ far too large.
Perhaps the biggest sin is that it relies on the young reader knowing Frida Kahlo – not every artwork, of course, but while what had caused her such injuries was on these pages, a lot was not clear about this drama possibly being formative for her presentation, outlook and so on. At the same time, while she's a main part of this story, in a nice sidekick-of-the-week manner, this would only need a minor tweak to be a book able to feature anyone; you'd have to change too little to make Frida's presence here far too inessential.
So yes, distinctive, dramatic and giving itself every opportunity to show Kahlo a new world and show a new audience Kahlo, but begging for a sounder production.
