This was quite a treat. I absolutely adore the book’s premise/setting, which is: certain mathematical operations have side effects that ripple through other universes, ergo Cthulhu.
This is basically a spy thriller/fantasy/sci-fi/lovecraftian story, where magic and the Old Ones are real, but you need heavy computations or obscure mathematical proofs to interact.
I was never much into horror in general, so the Lovecraft stuff mostly went by me, but this book just took that and put it in a context I’m much more comfortable with. It then tops it off with good writing, computer and maths references and a bit of humour.
The story feels like it ends a little abruptly (though it makes more sense as the first book in a series) and it’s not very heavy on character development, but I’ve enjoyed it very much and will definitely keep on reading.
As an aside, this can probably win the prize for the most uninteresting book and series title. If I hadn’t have multiple strong recommendations, I’d probably just pass it by.
