In the second installment of a renowned science fiction trilogy, humanity is faced with an impending alien invasion, set to occur in four centuries. The world turns to the Wallfacer Project, a strategic initiative that appoints four individuals with the power to execute plans to combat the extraterrestrial threat, their strategies hidden even from humanity to prevent the aliens from gaining foreknowledge. One of these Wallfacers, a disillusioned astronomer, devises a complex plan involving astrophysics, sociology, and game theory, all while grappling with the philosophical implications of a universe where survival is predicated on a dark forest theory, where civilizations are hunters lying in wait, ready to strike out of fear and self-preservation.
