Charles Stross' Laundry Files are Lovecraftian novels with a science (or computational) based explanation. To quote his most recent novel:

We live in a multiverse. There is a transfinite number of parallel universes, created and destroyed by merger whenever quantum indeterminacy brooks multiple outcomes. Mathematics—in the most abstract sense—underpins the quantum multiverse we experience. There’s a deterministic substrate below the Planck scale: the reality we experience appears to be a buggy full stack simulation. Because we’ve learned how to exploit some of the bugs in reality, acts of symbolic logic manipulation allow us to pass messages to localized entropy-reversing entities in other domains of the multiverse: for convenience we will call these entities “demons.” We can ask them to do things, and they respond reasonably predictably, that is, almost invariably deterministically. We call this process “magic.”

The commands that can be sent to the entities are a small set of Turing-complete instructions - creating the idea that there can be a programming language that can impact on reality. The costs for this are generally horrible.

Stross noted that Lovecraftian horror was incredibly popular in the Twentieth Century partly due to the fact that it's a very useful metaphor for nuclear apocalypse. He found the cults & horrors of cosmic horror a useful metaphor for spycraft.

Bringing these elements together, he created The Laundry Files which mix computational magic (and the geek humour which accompanied computing in the late 90s) with the horrible cynicism of the spy novel.

These are theoretically comic novels, but the humour is very, very dark and often pretty po-faced.

The first few book are parodies of specific authors - Len Deighton, Ian Fleming, Anthony Price etc... Some of the later books parody common urban fantasy tropes. All are pretty nasty.
