The Freedom Factor by Gerald Lund

Nathaniel Gorham, one of the signers of the Constitution, appears to a young senator's aide to show him why a 27th amendment to the Constitution would be a bad idea. Bryce is taken to a place where the Constitution was never ratified, and shown how precious the country's form of government is, and how much we take the check and balances of this government for granted.
