The Handmaid's Tale, by Margaret Atwood. This is one of those classic books that I've meant to read for decades, but only recently got around to it. I didn't really know what to expect, but I was pleasantly surprised. The story is chillingly unnerving, the writing poetic and efficient.
The novel's cautionary political and feminist message is no less relevant today than when it was written. But I like that Atwood conveys her message through the strength of the story and her relatable protagonist, as opposed to dogmatic exposition and characters that serve soley as mouthpieces.
