This sequel to Lessing's futuristic novel Mara and Dann continues the saga of Dann, the refugee boy prince of the Mahondi, who searched with his older sister Mara for habitable land on a planet Earth beset by a new ice age. Several characters from that novel reappear, including Griot, a soldier who served under Dann, but Mara has died in childbirth. Grief deafens General Dann to the pleas of those who believe he alone can save civilization from the warring chaos of displaced populations. Lessing's long literary career includes much science fiction (the Canopus in Argos series), but this dystopia, underscored by its reluctant hero's existential dilemma—why go on just to go on—resembles a classical myth, albeit one with no gods to intervene. As Dann disastrously tries to assuage his grief with opium, loyal Griot raises an army and finds a repository of books that preserves the wisdom of lost civilizations. Less of an adventure story than its predecessor, this sequel requires patience through several repetitive passages devoted to Dann's refusal to act. But that is a small price to pay for Lessing's acute observations.
