As per my usual with thrillers, I thought it was fine, but not anything I was SO EXCITED to keep reading. I keep trying different titles that trusted reviewers love, hoping I'll really enjoy a thriller. Alas, there's something about most of the books in the genre that feel drawn out and repetitive to me.
The atmosphere and creep factor were engaging, but I kept getting the various victims and suspects mixed up, especially since the two timelines mirror each other (which also lent itself to the repetitive nature of the plot being laid out in the past and rehashed in the present day).
There were also some super detailed bits that went nowhere. Who were some of these ghosts besides Betty?? What was with the red herring of Nick's traumatic past - SO much page count dedicated to this, WHY? And why do we have to slap together a romance? And a random antagonist out of nowhere at the end? 
Not my cuppa, obviously.
