I couldn’t put this down. I assume because of the ease of the writing style, but also the story itself, which is a fairly interesting premise. 

Mallory isn’t the most likable character, but she’s the second best of the bunch. (Adrian is the best, but doesn’t get enough development.) There’s some inconsistency in her character development. We’re told she’s religious and that she has issues with memory. Other than her wearing a cross necklace and possibly attending church outside of the book, there’s not much religion to her. The memory issues are presented as a reason to doubt Mallory’s side of things, but they don’t appear other than in mention. There’s no evidence of memory issues.

There are other moments of inconsistency with Rekulak’s writing. In one scene Mallory’s sponsor is drug testing her. Mallory grabs a paper cup. Then the cup is plastic. Then the cup is paper again and she’s now having to take it from her sponsor. It’s a very small point, but these inconsistencies frustrate me when I discover them.

I expected more horror, but think it is more mystery/thriller with horror elements. That’s probably why I enjoyed it as much as I did. 

One thing I definitely appreciated is that the flash forward isn’t a quick wrap up. There’s a bit more depth to it than you’d usually get. That makes it feel more complete.
