Momma had always told Susan that there was no safe place for a Jew, especially in German occupied Hungary in 1944. Why then were twelve-year-old Susan and her little sister, Vera, being sent to a convent to be kept safe. Susan and her sister soon discover the true nature of courage, sheltered by a group of nuns who risk their lives to protect them. Based on true events, the Guardian Angel House was the nickname given to a convent operated by the Sisters of Charity in Budapest. The nuns there sheltered over 120 Jewish children during the German invasion of Hungary, including author Kathy Clark's mother and aunt.

Kathy Clark was born in Budapest, Hungary, and moved to Canada as a young girl. She based this book on the true story of her mother and aunt after hearing their amazing story. She lives in Ontario, Canada, with her family.
