Timeline by Michael Crichton

When a group of scientists learns how to travel through time, they enter life in fourteenth-century feudal France and threaten the history of the world.

Recommended by Mr. Halacy, Social Studies Teacher: "Timeline blends science fiction with history. Other books I recommend by Michael Crichton, Andromeda Strain and Terminal Man, are a little outdated but are relevant today as Andromeda Strain deals with an incurable plague and Terminal Man deals with a man surgically altered to control his behavior.”
