Here are the books I was talking about in my homily yesterday:
Fr. Walter Ciszek’s books
With God in Russia – https://amzn.to/2KjQV2y
He Leadeth Me – https://amzn.to/2KlowJm
If you want the full deal you should read the “With God in Russia” first it is more biographical, and then the second one has more of the spiritual lessons distilled out.
Although, you can also just go to Formed and search his name and you will find the books there on audio along with a short film.
