I picked this up on a friend's insistence and finished it in two sittings, annoyed at myself for needing sleep in between. Gillian Flynn writes about a marriage that looks perfect from the outside and absolutely is not, and she does it through two voices that you slowly realize you can't fully trust. This is one of the best psychological thriller books precisely because it isn't really about who did what — it's about how two people construct a version of themselves for each other and what happens when that construction cracks. Read it when you want to be a little uncomfortable, when you want a book that makes you suspicious of your own assumptions a hundred pages in. Flynn's sentences are sharp and often very funny in a way that catches you off guard given how dark the material gets. I'd recommend this for anyone who thinks they've figured out a thriller too early; this one is built specifically to prove you wrong, more than once. It's also, underneath the plotting, a genuinely mean and accurate portrait of resentment inside a relationship, which is part of why it stuck with so many readers beyond the twist everyone talks about. Don't read reviews or synopses beforehand if you can help it — half the pleasure is not knowing which direction it's about to turn. Pour a drink, clear your evening, and don't answer texts. This is not a book you want interrupted.
