Reading material - sci fi

It's my birthday, don't tell anyone :-) Reading material - I got my hands of some very good stuff!!! Science fiction, from the 1930, at the level of Orwell's 1984. Very cool, really,I love when someone has the vision of the perfect society and rubs it under your nose to show you how fundamentally wrong the concept is! So, I am reading Aldous Huxley's Brave New World. Excellent read. Highly recommended, in case you have not read it yet! Also, as a follow up: I just hear about the The Handmaid's Tale by Margaret Atwood. Still need to get it, but I think I am on to some pretty impressive stuff here. If you know of similar stuff, stop being so mean and share it! Looking for some out of the box science fiction! Thanks a lot in advance.
