What is The Moon Is a Harsh Mistress about?
Luna, 2075: a penal colony shipping grain to a hungry Earth down a gravity well that makes revolt apparently suicidal. Computer technician Manuel O'Kelly Davis discovers the lunar master computer has woken up and developed a sense of humour; together with the agitator Wyoh and the aged anarchist Professor de la Paz, man and machine engineer a revolution, with Mike the AI as invisible commander-in-chief and rocks as the ultimate artillery. Narrated in clipped Loonie creole, it is Heinlein's tightest novel and his most sustained political thought-experiment ('TANSTAAFL').
Why it matters
Hugo winner (1967), the canonical libertarian SF novel, and home of the most beloved AI character of its era. Its lunar-catapult warfare remains standard orbital-mechanics furniture.

Forever Peace
Hugo, Nebula and Campbell Memorial winner — one of the rare books to take all three; its remote-warfare and forced-empathy arguments only grow more current.
