H. Kaur lives with her family in Toronto. Born and raised in England, she immigrated to Canada and completed a B.A. (Hons) with a Distinction in History and Political Science at the University of Toronto. As an undergraduate student, she learned about various devastating acts of genocide. Also as a teenager, she read Anne Frank's diary and pondered how people become apathetic to human rights, devoid of compassion, empathy and humanity. She has often wondered why society throughout history, did not prevent or stop mass atrocities from occurring again, and again.
The genocide that inspired the author to write When the Sky Was No Longer Blue took place in the 1980s. The book is the product of interviews with people who knew of survivors and their stories, and of written testimonies about what the survivors endured. Seeing a rise in hate globally, she felt it was time to share this story and showcase how we all can learn from history.
