I was disappointed by it, more so now time has passed than when I first finished it. I think it left a lot of unanswered questions that made reading it a bit pointless.
I thought there were a lot of leads that were never followed, a lot of directions it could have gone in but none were really followed up on.
It's like the author had a lot of possible endings in mind and couldn't chose between them, so he just left it.
It could have been so much better, the landscape was creepy and atmospheric but not really made the most of, the shrine could have offered an explanation but didn't, there could have been more to the hidden room but once we found out about it then nothing more was really discovered, the weird local custom play could have revealed some kind of weird horrible tradition that explained things, we could have learned more about the girl in the other house, for example was she the first girl or had there been lots before, or had she previously been taken there to have a baby before this one, there could have been more about that house and it's history and what happened in the cellar, and why did the boy/man narrating (can't remember his name) have to start following his brother about when he saw the house on the news years later? What did he think was going to happen, and how did he think he might prevent it?
I read another book recently that left me with a lot of unanswered questions, The Death House by Sarah Pinborough, and someone on here said that if you finish a book wondering this much about it, it's bad writing by the author even if the book was good. I've started to think they are right about that. It doesn't matter how well written it is, if you feel you've missed all this much from a book they really haven't done their job properly.
I can't see me ever wanting to re-read either of them and it's a shame because I had high hopes for them both. Instead I've filed them under "good idea but not followed through" and given them up as a bad job.
