So, I only ever heard about this novel because I watched the show that was adapted from it back when it aired on BBCA in 2014. This book has been on my "want to read" list ever since, but I was hampered from reading it by the fact that no libraries I was a member of had it in their catalogue. Then I started checking out most books from the library via the e-library Hoopla (due to the pandemic), and they actually had it! So, I was finally able to read a book that inspired a show that I enjoyed, but honestly didn't remember much about six years later. (All I remembered was that John Simm, my favourite actor, starred in it and that there was a creepy little girl that was murdering people and saying 'What goes around, comes around!' all the time. And that dead people were stealing living people's bodies, but I could not remember why they were doing it or how the show had even ended.)
In terms of strengths, this book has a wonderful, foreboding atmosphere. I've never been to the Pacific Northwest, but the descriptions of the weather and the overhanging clouds just fed into the feeling of paranoia and strangeness. Also, because I only remembered the major turns of the story, there were some genuine mystery moments that drew me in. I knew they were in the show, but I couldn't remember what the answers were, so I got to experience certain of the story for the first time, all over again. Also, in the show, the character Madison (played by a VERY young Millie Bobby Brown, back before Stranger Things had made her a superstar) was JUST wonderfully creepy, but because we never really got to see her POV in the show and saw more of the crazy Intruder that was using her body as a vessel, I never cared much what happened to her in the show. In the book, we see inside Madison's very confused 9 year old mind and it is heartbreaking to see how hard she fights to maintain control of her very young life, and shows that kid is a mega badass for how hard she fights back.
I also only vaguely remembered the character of Gary Fischer and, honestly, I think maybe his character was severely diminished in the show. In the book, I was gripped by his backstory and the gradual reveals we got about what drew him to contact main character Jack Whalen. I don't remember anything about him in the show though. I can't even put a face with the name.
In terms of the negatives, there is a lot of info dumping. While the mystery is fascinating, all the answers seem to come in huge blocks and then 70 pages of nothing really and then another huge info dump. And when you have all the answers, you're just kind of left throwing your hands in the air, and going, "okay, now what?" You feel a bit for Jack because things end more on the bitter than the sweet side for him, and the man at least got his answers, but...at what cost? And Madison's story just kind of ends and while you hope it's a good ending for her, the feeling of uneasiness still pervades for me and I think she was actually still possessed. I hope I'm wrong, but Jack never really looks too deeply into finding out if she was genuinely as okay as she seemed.
It's strange though. The book did a much better job of making me like Madison than the show did; but the book left me feeling that Jack was kind of a cardboard cut out character. His reactions at the end make little sense, except that the man had been put through the emotional wringer and was probably just in shock. It's the only way I can account for his dissociative behavior in the last forty pages of the book. Also, I was spoiled by having John Simm play Jack in the show and the emotional note he brought to the character is hard to match in book form. However, Jack's thoughts on human nature and our views of death and grieving are legitimate and interesting. So, props to the writing style on the introspective bits.
Also, I feel like Michael Marshall must have had the Billy Joel song "The Stranger" playing on repeat while he wrote this novel because the plot of this book is basically that song's entire premise.
