Is there life on Mars? Yes—in Kurt Vonnegut’s fantastic novel “Sirens of Titan,” the reader can visit not only Mars, but also Mercury and Titan alongside the main character, Malachi Constant, a wealthy American who burns through his life. On Mars, Malachi is reborn as “Uncle,” loses his memory, loses everything, and must carry out orders from people who embedded a chip in his brain that causes him unbearable pain whenever he refuses his boss’s commands. You’ll be in for an utterly incredible plot, thrilling space adventures, and—at the same time—complex philosophical reflections, a rethinking of moral, religious, and aesthetic values, and an attempt to find the meaning of life.
