Fifteen years after the events of The Handmaid's Tale, the theocratic regime of the Republic of Gilead maintains its grip on power, but there are signs it is beginning to rot from within. At this crucial moment, the lives of three radically different women converge, with potentially explosive results. Two have grown up on opposite sides of the border: one in Gilead as the privileged daughter of an important Commander, and one in Canada, where she marches in anti-Gilead protests and watches news of its horrors on TV. The testimonies of these two young women, part of the first generation to come of age in the new order, are braided with a third voice: that of one of the regime's enforcers, a woman who wields power through the ruthless accumulation and deployment of secrets. Long-buried secrets are what finally bring these three together, forcing each of them to come to terms with who she is and how far she will go for what she believes.
