SOLVED. YA Horror book involving multiple main characters that flee to an amusement park after being targeted by zombies. Spoilers. [s]

[Elean]

I read this book somewhere between 2020 and 2022, and the blurbs on the back described it as a zombie book even though the people weren't exactly zombies. I think the POV switched between the multiple main characters, all of which fled from their homes after everyone around them became seemingly possessed and started attacking them. I don't remember any of the character's names, unfortunately, but I believe the cover was mostly red? The book was also really thick, which is why I wasn't able to finish it in the two weeks I had before returning it to the library. SPOILERS AHEAD.

I'm very new to the site, so apologies if I did the spoiler html tag incorrectly.
(view spoiler)[ At some point on their way to their destination, there was a car crash that resulted in an explosion, if I remember correctly. I also think one of the main characters had a girlfriend who was possessed and turned on him, so he locked her in the basement I think. The characters eventually found out that they were possessed by angels, which is why they were being attacked. There was also some guy in either a hospital or morgue who was originally separate from the main story, but eventually turned into a giant demon / black hole or something. The main characters got in touch with the angels possessing them and tried to fight the demon, but I never found out what happened after that. (hide spoiler)]
