I really enjoyed the first half of this book. It was well paced and super intriguing, I like the interview/screen play additions to really help set the crappy mood. Josie and Alix felt like real people, definitely something off about both of them which added to the suspense. 
I got a little bored in the middle, and then I started to not like it so much as the mystery started to become clearer. I don’t love an ambiguous ending, but with unreliable an narrator(s) it probably made the lost sense. 
I like the story, o read it in a day, but felt a little unfulfilled with the ending
