On a dark, wet evening in Dublin, scientist and mother of four Eilish Stack answers her front door to find two officers from Ireland’s newly formed secret police on her step. They have arrived to interrogate her husband, a trade unionist. Ireland is falling apart, caught in the grip of a government turning towards tyranny. As the life she knows and the ones she loves disappear before her eyes, Eilish must contend with the dystopian logic of her new, unraveling country. How far will she go to save her family? And what --- or who --- is she willing to leave behind?

Early one October morning, Grace's mother snatches her from sleep and brutally cuts off her hair, declaring, "You are the strong one now."

When her younger brother Colly follows after her, the two set off on a remarkable odyssey in the looming shadow of their country's darkest hour. The broken land they pass through reveals untold suffering as well as unexpected beauty. To survive, Grace must become a boy, a bandit, a penitent and, finally, a woman --- all the while afflicted by inner voices that arise out of what she has seen and what she has lost.
