Catherine Ho was born in Shanghai in 1936 of non-Catholic parents. At the age of 14 she was baptised into the Catholic Church and shortly afterwards joined the Legion of Mary. She was arrested for the first time on September 8th, 1955 on account of her religion and spent one year in prison. On her release she worked in a factory and was known to her companions as "little Lark" - whence the title of the book. She was again arrested on October 10th, 1959 and spent 20 years in different jails and labor camps. Despite her intense suffering, both physical and psychological, during those years, she retained her human dignity and her Catholic faith. She was released from the last camp in 1979 and left China. She lives with her husband in the USA.
