This was a quick domestic suspense. It is an updated retelling of Rebecca but I haven't read that so I can't speak to hwo well its done in an adaptation. The book is split into 2 parts (almost exactly halfway through) with the pacing of the second being much faster than the pacing of the first half. While you still get that eyeroll at a few moments, the book is set up in a way that you can understand the reasoning that Angel makes the choices she does.

There is a lot of clear commentary on class differences and what people will do to get ahead (or to be perceived as being ahead). While the book is named Chloe, I would say only 25% of the book is about the actual mystery surrounding Chloe. In true gothic fashion, the primary of the book is building the tension and leading the character to be willing to confront that something is wrong here.
