Sometime in 2015-2017, I read the first chapter or so of a trade paperback book. The cover included quite a bit of red. The name might have been the name of the main character. It was most likely American, but it might have been British.
It was about a man, I think with supernatural abilities, going to Hell to try to get something from Satan. It really detailed Hell a lot. The first chapter talked about how there were lots of naked, newly dead people walking in at the same time as him. I think Satan had a throne that was described. The man had the power to go back and forth without dying, I think. I feel like maybe he was investigating something.
It wasn’t Demon Road by Derek Landy.
