Several years ago, Michael Dubruiel edited a prayer book centered on Fulton Sheen's writings. It is out of print, but there are a few used copies available at reasonable prices here:
From an Amazon review:
We are fortunate to have a Chapel of Perpetual Adoration in a nearby town (Shinnston, WV) and I was looking for something to read during my weekly hour visit. I ordered the book because I had always heard about Bishop Sheen but had never read any of his works. He was from the `before my time' era. Would it apply to my life? Well, so far I've only read the first 3 chapters, and WOW it hits me right where I am in my prayer journey. Our God is so remarkable, transcending time and space to meet me through the pages of this book. If you are looking for something to bring you to the Lord, this book is it. It has just the right amount of information to spend an hour in quiet prayer time (maybe less). Each chapter has part of one of Bishop Sheen's sermons (or excerpt from a book) and a reflection and then some thought provoking questions. This is one book I am keeping!!
