This is a novel about toxic relationships, obsession and self-destruction. The protagonist is fairly unlikeable from the start, but in a way that I still found enjoyable to read. I really liked the pacing of the book, rather than being very quick with major plot points it slowly built up the relationships and the steps towards the inevitable end, and that isn't always easy to do. The little ways in which insecurity can spiral over time, how small reasonable-seeming curiosities can build on each other into obsession, felt very real.
