When Jane Mooney's older brother Connor lies about his age and enlists in the Great War at age fifteen, she can't imagine ever being more devastated. But on December 6, 1917, when two ships collide in Halifax Harbour, the resulting explosion proves her wrong. An injured Jane awakes to discover that the North End of Halifax, including her home, has been destroyed; her father and three of her brothers have been killed; her mother, recovering from a head injury, has been left confused and forgetful; and her two surviving brothers are looking to her for guidance. Like so many Explosion survivors, Jane and her family are forced to start over. This means accommodation in a newly-constructed apartment block, clothing and furniture from donation centres, and a new school. Unfortunately for Jane, the school she must now attend is in the prosperous South End. How will she fit in with her uppity classmates?
