The 4 stars for enjoyment and 1.5 stars for quality is really all you need to know. There were multiple times when I cackled out loud at how ridiculous something was, and it helped me get out of a reading slump. What more can you ask for from a bad thriller?

Overall, a mediocre thriller. It was fine and I finished it very quickly, but I don't feel like it has left a strong impression on me one way or the other.

The writing is serviceable. The characters mostly have distinct voices, although there is quite a bit of head-hopping where we are in one character's POV and then abruptly switch over to hear what someone else is thinking for a few sentences. That's particularly jarring if you listen to the audiobook, since each POV character has their chapters read by a different voice actor, so it's very noticeable when one narrator is saying things that their character technically shouldn't know.

The plot is exceedingly simple as thrillers go, with very few twists. That's not inherently a bad thing, but I do think the marketing set this book up to disappoint readers. Because of the cover and title, domestic thriller fans will pick this up with a set of genre expectations that this book does not really fulfill. I think many readers (myself included) would have been much more satisfied if there was some dramatic revelation towards the end, because that's the convention in this genre. That doesn't really happen, though. This book tells a story which is sad and somewhat mysterious, but not mysterious in a fun whodunnit way. It's mysterious in the way that many real life crimes are, where you know more or less what happened from the beginning, and maybe some more clarifying details are revealed over time, but you may never get the kind of sense of closure you'd like. I don't think that's a bad way of writing this story, necessarily, but it's not the best thing if you're trying to sell a domestic thriller that could be picked up by fans of Gone Girl or The Girl on the Train or The Housemaid.

Also - the description doesn't make this clear, but the main plot revolves around child abduction and CSAM. Not in particularly graphic detail, but if you'd like to avoid those themes, you'd probably better skip this one.
