I had never of C.T. Studd before this book, and by the end, I didn't really care for him. C.T. comes from a rich family. He is a star cricket player and is planning on an easy life being an athlete. While he's in school, his father becomes a Christian. When C.T. and his brothers are home from school, their father constantly bothers them to also become Christians. Eventually, C.T. does, as do his brothers.
He becomes more devout through the years and eventually abandons his cricket career to become a missionary. When his father dies, he inherits a great deal of money, which he promptly gives away.
While there's no doubt of C.T.'s impact on the mission field, by the end, I found him extremely annoying and hard headed. He was continually ready to sacrifice his family, his time with them, and his relationships with them for his own beliefs.
