From the Catholic Company, we have The Pope and the CEO, the personal testimony of former Swiss Guard Andreas Widmar and his reflections on the leadership principles of Bl. Pope John Paul II. It is a fun read, providing unique access to the hidden, daily habits of one of the greatest men of the 20th century. Widmar saw the pope interact with housekeepers, dictators, presidents, nuns, and people of every faith on the globe. After his service in the Vatican, he went on to become a business leader in Europe and America. He stopped practicing the faith, but after making millions returned to the Church largely because of his memories of John Paul. His story in itself is enough to make the book worthwhile.
Widmar structured his chapters on different themes in the Christian life: self-knowledge, prayer, detachment, community, and moderation, to name a few. In terms of spiritual reflection, the book is probably best for someone just starting to explore or return to faith in Christ. Each chapter ends with three or four questions for personal reflection, making it an ideal book for a reading group, Bible study, or men's group.
