In an attempt to appeal to the Medici family during the Italian Renaissance, Machiavelli outlines the way to acquire and retain political power, and how great men should behave in a princely government. The book is divided into four parts - types of principalities and state, proper conduct of a prince as military leader, personal conduct of a prince, and the disparity of Italy's political situation. Many listeners will be able to see principals that Machiavelli advocates for are still used in many political systems today.

In this lyrical and moving novel, Philip K. Dick intertwines the story of a toxic love affair with one about sentient robots, and unflinchingly views it all through the prism of mental illness - which spares neither human nor robot.

When Louis Rosen’s electronic-organ company builds a pitch-perfect robotic replica of Abraham Lincoln, the firm is pulled into the orbit of a shady businessman, who is looking to use Lincoln for his own profit.
