Somewhat of spoiler below. I read The Push by this same author and really enjoyed that horror book. Even the ambiguous ending. I thought I would enjoy this one too. Problem 1: I listened to it on audiobook. They should have had different women narrating their POVs. It took me an embarrassing number of chapters to have the characters sorted in my head. Problem 2: the timeline also jumped around a bit between present day and before the fall. Problem 3: there were so many chapters that dealt with the various minutia of their lives (eg: what was the point of Mara???) that I struggled to pay attention. Finally: spoiler….

Problem 4: All this only to not really get a definitive ending. Again. You find how he fell but not what he remembers, and what he’ll do with it.
