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. The end result is one of Dick's most quietly powerful works. 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. Meanwhile, Rosen seeks Lincoln's advice as he woos a woman incapable of understanding human emotions - someone who may be even more robotic than Lincoln's replica.
