After a solar flare upended the world order, Kwesi Brackett's life disintegrated. His wife took up with a millionaire in the heavily armed Silicon territories and his daughter's university, Yale, relocated to the Caribbean. After being laid off by NASA, Brackett finds himself in Africa, as one of the head engineers for the newly formed Nigerian Space Program. Suddenly, the NSP's goal of getting astronauts into space is more important than ever. With most of Europe, Asia, and North America knocked off-line, thousands of satellites about to plummet to Earth, and the political minefield that is the rescue of an international group of astronauts trapped on the international station, time is of the essence. The deranged and violent militant group Boko Haram is steadily approaching, and the last surviving members of the Fulani tribe, an ancient matriarchal nomadic society, have found refuge in the abandoned caves of the Saon people. Accessible only by sonic vibrations, the sophisticated cave system contains messages from the past in a series of astrolabes, powerful amulets whose destructive force is harnessed by the Fulani tribeswomen. The astrolabes, it turns out, hold the secret to the Saon people's extinction, and clues about a different flare that rocked Earth thousands of years ago. When a mysterious creature breaks into Brackett's quarters, the engineer is not sure whether it was a rival space program or the government as they race to complete the Naijapool--an anti-gravity simulation to train the Naijanuats. In over his head, Bracket is distracted only by his favorite reality show Mrs. N Fires the Help and his affair with scientist and music enthusiast, Seeta. Increasingly, however, Nigeria's past and present are threatening to collide in a battle over its own future, and Bracket and Seeta seem to be the only ones who suspect it is all connected. Enter Wale Olufunmi, the original protagonist of Nigerians in Space. A former lunar geologist who continues to dream of participating directly in a space mission, Wale lands at the Nigerian Space Program facility, on a private jet. When Brackett, Wale, and Seeta discover the Fulani women's hideout, and the power of the astrolabes, they band together to outmaneuver Boko Haram, save Nigeria from a sinister government conspiracy, and finally launch a spacecraft.
