I enjoyed this book. It had immediate personal relevance, kicking off in my old-university city of Nottingham! In the 90s, a little while before the time I was there studying physics. With its central female protagonist called Laura (weirdly also the name of a girlfriend I had there), its brief summary of her mundanely relatable romance spoke truth to me, too. Anyway...
"Ra" initially presents as a kind of alternate history, where magic exists as a new kind of science. Only recently taught to undergraduates, in either applied or theoretical courses. Described as esoteric and remote, for the majority of the population. Much like quantum physics in the real world. In both cases, they've been quietly revolutionary for civilisation.
Our protagonist makes the exception to this, with ostentatious, hyper-competent implementation of its possibilities. Magic is cast by speaking a kind of programmer pseudo-code, with an ancient Samarian (or some such) flavour. While simultaneously holding complex concepts in mind.
It's no coincidence there's an echo of "The Laundry Files" mathematical demonology, here; qntm has clearly been strongly influenced by several of my favourite sci-fi authors, including Charles Stross, who's tweet put me onto them in the first place.
