The Rook by Daniel O'Malley (Amazon). I think the MC has some powers, but I can't remember what it is, so its clearly not a big deal. The MC is part of the UK's secret supernatural agency, e.g. SCP (but not quite as outlandish).

This is some of the most creative writing I’ve ever seen. From memory, the first line reads “Dear you, the body you’re wearing used to be mine.” I’d check, but my copy’s being read by my neighbour right now. There was a TV series made of it but it really doesn’t compare. It features a host of unique characters, including Gestalt - who is 4 siblings that have a single mind. It’s fast paced, action and intrigue-packed, and accessible (I hate all those sci-fi novels with unpronounceable names filled with apostrophes). Don’t be put off by its size, there’s so much going on you’ll enjoy the ride. It feels like the author had a great time writing it. And just a tip - not just for this book but in general - if you want to start reading and aren’t used to it, just tell yourself you’re only going to do it for 10 minutes. You’re brain will just want more. I hope you check it out; it’s so clever.
Could this be The Rook by Daniel O'Malley?
Lucky OP, you got good commenters. This thing has a good potential for trolling.
I'd recommend The Rook, from the top of my head.
I read The Rook by Daniel O'Malley when I was looking to fill the Matthew Swift shaped void in my life

First time author who had an interesting idea, but terrible execution.
