Listen! is the deeply personal memoir of Michael A. Casciano, a man whose ordinary upbringing gave way to an extraordinary lifelong practice — learning to hear the quiet, persistent voice of God and having the courage to respond. Raised in a devout Catholic household filled with love and encouragement, Michael spent decades reflecting on the moments — small and large — when he felt prompted to act and chose to do so. From an encounter with a homeless man that left him walking on air, to the pivotal relationships and turning points that shaped his life, he came to see a clear pattern: God was always speaking. The question was simply whether he was willing to listen. Written after years of discernment, this book is not so much the story of who Michael is, but of what he learned to do — pause, pay attention, and respond. It is an invitation for readers to do the same.
