I've done the 33-day consecration to Jesus through Mary before, and it wasn't too bad. Using Fr. Gaitley's book, though, was amazing. If I had let myself, I would have whipped right through it--the writing is accessible and down-to-earth and relevant to modern readers. Gaitley tapped into four great Marian saints and transformed the consecration preparation into a whole new experience for me. His explanations and insights were smack-my-forehead good and somehow, they stuck with me. I couldn't recommend this more. If you read one book this year, let it be THIS one.
