This book was well written and interesting. The pacing was good, with a pervading sense of creepiness throughout the pages. The author placed a couple of good red herrings, yet also marked the trail to the reveal with plenty of deeply seeded hints.
That said, it’s been done before. The plot, that is. I kept waiting for some great turn of events to fishtail the reader’s investigation (because that’s what we do while reading mysteries, right?) in a completely different direction. But it never happened. The theory I postulated early on became fact. I would have preferred a wilder end to this piece of fiction. It’s definitely worth reading, but I wish the author had written a fresher ending that didn’t feel so overdone. For that, I give it 4 stars.
