…And Now Miguel by Joseph Krumgold
Miguel wants desperately to go with the men on the long sheep drive in the summer, but his father thinks he is too young. Miguel does everything he can to prove himself to his father, but his father's answer is still no. Finally, Miguel resorts to praying to the saint, begging the saint to find a way for Miguel to go on the drive.
Miguel does not anticipate the consequences of his prayer. His father changes his mind, allowing Miguel to go, but at what cost, for what reasons?
This book is a thoughtful look at a boy growing to become a man, suddenly seeing things that were once clearly black or white have become a frightening gray.
