In 1966, twelve-year-old Chanie Wenjack froze to death on the railway tracks after running away from residential school. An inquest was called for and four recommendations were made to ensure the safety of indigenous students. None of those recommendations were applied.

More than a quarter of a century later, from 2000 to 2011, seven indigenous high school students died in Thunder Bay, Ontario. The seven were hundreds of miles away from their families, forced to leave home because there was no high school on their reserves. Five were found dead in the rivers surrounding Lake Superior, below a sacred indigenous site. Jordan Wabasse, a gentle boy and star hockey player, disappeared into the -20 Celsius night. The body of celebrated artist Norval Morrisseau's grandson, Kyle, was pulled from a river, as was Curran Strang's. Robyn Harper died in her boarding-house hallway and Paul Panacheese inexplicably collapsed on his kitchen floor. Reggie Bushie's death finally prompted an inquest, seven years after the discovery of Jethro Anderson, the first boy whose body was found in the water. But it was the death of twelve-year-old Chanie Wenjack that foreshadowed the loss of the seven.

Using a sweeping narrative focusing on the lives of the students, award-winning investigative journalist Tanya Talaga delves into the history of this small northern city that has come to manifest Canada's long struggle with human rights violations against indigenous communities.
