Reading & Reflection

Books That Shaped My Thinking

Between voyages across the Mediterranean, Aegean, and Ionias seas, where the horizon stretches unbroken and the mind finds its clearest perspective — I have always kept a book close at hand. The sea teaches patience and systems thinking; the books I return to most often do the same. This is my curated reading list: the titles I recommend to colleagues, the ones I revisit, and the ideas that continue to influence how I lead and think about cybersecurity.
