Overall, I found this to be a very compelling thriller, with a strong cast of characters, a good mystery, and a fascinating premise. Without spoiling how it goes, the climax of this book had such a hold on me that I kept having to put it down, walk a lap around the kitchen or holler at my mother about it, and then come back to get right back to reading. I especially liked our main characters: they were both fully fleshed-out with clear motivations and flaws that felt realistic for their age and experiences. I especially loved Carolina's experience with intrusive thoughts (the book never exactly names them as that, but I certainly interpreted them as such and really appreciated that representation and how it was handled!) and she was probably my favorite, though I absolutely loved Lucy, too. I also felt like it did a really good job of capturing the true-crime community and what draws people to that kind of thing, with balancing the understandable reasons people might enjoy it with Lucy''s well-earned hatred of the genre. The mystery felt satisfying and like it was well-resolved, and I ultimately really enjoyed this book and think of it often!

Still, one major spoilery thing brought the rating down for me:

the fact that we clearly have a trio of main characters in Lucy, Carolina, and Maggie, but the fact that we only get Lucy and Carolina's perspectives made me immediately suspicious of Maggie. While I do like a thriller or mystery to lay out plenty of clues to me, I feel like this pretty noticeable choice made me immediately suspicious of her from, like, just the first few chapters, which made it a little too easy to guess her as the primary culprit from just a little too early. I definitely would've liked to be kept wondering a bit more, but this choice just felt a little too conspicuous to me, since the girls form a trio pretty early on, so I instantly wondered why we didn't have Maggie's perspective. I know there's a lot going on with Lucy and Carolina's perspectives already, but I feel like having Maggie's (at least early on, I think it could successfully fade out as the plot continued without being too obvious) perspective would keep the reader guessing about her more, and would also offer a super interesting insight into her character and motivations! That just brought it down a bit for me, especially since I don't consider myself to be the best at solving mysteries. Not a negative point, but still as a spoiler, I loved the fact that the fog was actively malicious! I love a bit of supernatural stuff going on in my thriller/horror, especially if it's nature-based. This also made me realize that I'm definitely a bit more superstitious than the average person, because if someone mentioned evil fog and weird things started happening, I would literally just assume it was the fog, hands-down.

This is definitely worth a read! I was on the edge of my seat and definitely drawn into the atmosphere of this one.
