This book was pretty solid. I liked the narrators, and I especially liked the PDF evidence files interspersed throughout the chapters. It was an interesting way to navigate the story. The plot had a really great narrative overall, it was a wonderful idea. I do feel like the execution was not perfect. I didn't mind the ambiguity at the end, but at points the story just felt unpolished. It drew me in, but then dropped me a few times, until at the end of the book I was like... oh okay...
