The Moon Is a Harsh Mistress — Robert A. Heinlein
The Moon is no longer just a colony. It is a prison, a frontier, and a powder keg. When a computer technician, a political agitator, and a strangely self-aware supercomputer join forces, a scattered population of lunar exiles begins plotting revolution against Earth’s rule. Fast-moving, clever, and full of Heinlein’s trademark arguments about freedom, responsibility, and rebellion, this is one of the great political adventure novels of classic science fiction.
1632 — Eric Flint
When the small town of Grantville, West Virginia is suddenly transported to war-torn seventeenth-century Germany, its residents find themselves surrounded by mercenaries, monarchs, plague, and chaos.
