One summer night on a side street in downtown Toronto, Kim Lystrander is attacked by a stranger. Thrown deep into turmoil, in the weeks and months that follow, she confronts her fear by returning to the night, in writing, searching for harbingers of the incident, and clues to the identity of her assailant. The attack also torments Kim's father, Harold, an historian of Latin America. As he investigates the crime on his own, the darkest hours from his past revisit him, and he gradually begins to unravel. Entwined in their story are Kim’s ailing mother, Marian; Father AndrÔe Rowe, whose mission to guide others involves him in a decision with troubling consequences; Rodrigo Cantero, a young Colombian man, living illegally in the city; and Rosemary Yates, a woman whose faith-based belief in the duty to give asylum to any who seek it, even those judged guilty, draws Harold to her, before a fateful choice changes the future for them all.
