I don't remember where we got this book but it has long been a favorite with the children. It's really nice for reading aloud since each chapter is one or two pages of text with a beautiful illustration. I love books that make saints real to the children instead of portraying them as fantastical storybook characters. St. Josemaria's childhood is a wonderful example of the dynamic virtue so characteristic of children who love Jesus.
