Attempting to rise above the secrets of her past, Bolanle, a university graduate, marries Baba Segi, who promises her everything in exchange for agreeing to become his fourth wife. Thus she enters a polygamous world filled with expensive clothes, a generous monthly allowance, and three Segi wives who disapprove of the newest, youngest, most educated addition to the family. Among them are Iya Femi, a fiery vixen with a taste for money; Iya Tope, a shy woman whose kindness is eclipsed by terror; and Iya Segi, the first—most lethal and merciless of them all.
Bolanle quickly becomes Baba Segi's prized possession—until her very presence unlocks a secret the other wives have long since guarded, and unleashing it could change their lives as they know them.
