He Leadeth Me by Fr. Walter J. Ciszek, S.J.

This is a companion book to Ciszek's With God In Russia, an account of his years as a priest in the Soviet Union (much of it spent as a prisoner in the Gulag.) He Leadeth Me is a discussion of the spiritual lessons Fr. Ciszek learned during his years in Russia.  It is a wonderful read, simply and humbly written, with the wisdom that can only come from great suffering enlightened by deep faith.
