One of my favourite books of all time is by her: The Dispossessed.
It "features the development of the mathematical theory underlying a fictional ansible, a device capable of faster-than-light communication, which can send messages without delay, even between star systems." [1]
It doesn't get better than that. Certainly not "harder".
