Another example of a book's premise being far more interesting than the book itself. You live on an island where you wake up one day and something from your life has just vanished. The first incident in the book involves birds, so everyone woke up and suddenly the concept of "bird" holds no meaning. You don't remember what a bird was, you don't know what a bird is, all knowledge of "bird" is removed by the Memory Police. Holding onto past concepts like birds, flowers, calendars, is forbidden, and it's considered taboo to reminisce or talk about items that have been "disappeared". As the book progresses, the disappeared items take the form of increasingly important and valuable things, and while disoriented and discomfited, the people are expected and encouraged to take it in stride and move on.

Certain people are immune to this, where they retain all memories and knowledge of things that have been disappeared, and if discovered by the Memory Police, these people are taken away and never seen again. Our main character is not one of these people, but does hide away her editor as he is one of these people. Romance blooms as romance does in books like these, and the editors tries his best to make the main character remember things that had been lost and realize how awful things truly are.

It's a very dystopian novel, and one without any real satisfying answers or conclusion. We never find out who or what the Memory Police act on behalf of, or why these things are being removed. I gather the novel is about how complacency is a creeping, insidious beast (the things disappeared start out innocuous and easily missed and slowly ramp up in importance and meaning as the story progresses), and that people should never just accept things as they are, but honestly the book came off boring and incomplete. This would've had more meaning if we had more reason to care about the people and their fate.
