"In the country of blind men, the one eyed man is a king."

Almost always, the advice offered by the EWTN host types (Protestant converts who think they invented sliced bread, that they are God's gift to Catholicism) is "a revelation" to the blind masses, but a waste of time for real Catholics who LIVE the faith. Those EWTN type teachers are one eyed men. I have a feeling that that book is good for the people of the world, but no revelation to any Catholic who LIVES the faith.

The question to ask is: What does that book have to offer for say a traditional Catholic who has LIVED the faith for 30 years and has raised 12 children to adulthood who are all traditional Catholics LIVING the faith like their parents taught them?

I am a cradle Catholic from a Spaniard line of Catholics that have been Catholics for who knows how long 1500 years? I was baptized as an infant, received my first communion at the age of 8, and was confirmed at 13, all before the Novus Ordo was invented. I left the church in my teens and went out to the world to have a good time chasing bikini clad girts on the beach till I was 42. My conversion at 42 came about by many means but the principle one was that I only sought truth, I was not seeking anything for me. Almost instantly God showed me the Latin Mass and 2 months later the SSPX, where by God's providence my priest was an old Capuchin ordained in 1952. In 3 years I built up a library of like $5000 worth of books  and some tapes and videos. Today, I look at my library, of say  1000 books, and there are only like 3 books that are what I would call conservative Novus Ordo or EWTN type books AND I only read a few pages of them and realized they were empty. All of my books are written by Saints, Doctors, Fathers of the Church, priests, and renowned Catholic laymen, all pre-dating 1950, most pre-dating the 1900's.
There are so many time tested Catholic books written by  Saints, Doctors, Fathers of the Church, priests, and renowned Catholic laymen from the beginning of the Church and  before the liberalism of the late 1800's, that one would have to live 5 lifetimes to read them all. Why would I go to a book about marriage  written in 2020 by a woman of whom I know nothing about?  

If one honestly seeks truth and are willing to give up everything that they love for it, they will find it.

This might be a good opportunity to propose alternative literature for marriage. Any recommendations?

First item that comes to mind is:

Casti Connubii (December 31, 1930) | PIUS XI

The education for a  proper Catholic marriage should have started long before the couple even met, it should have started from their infancy. The parents should have been teaching the couple all of this from the time of the very birth of the couple. 

Here's are just two books that if followed, will lead to a good Catholic marriage:

The Catholic Girls Guide, by Fr. Lasance
The Catholic Young Man's Guide, by Fr. Lasance

The Catholic Girls Guide, by Fr. Lasance
The Catholic Young Man's Guide, by Fr. Lasance

Parents should know these 2 books inside and out BEFORE the child is born and have a plan on how to implement them into the child's first 16 years.
I especially like the boy's book with it's description of putting on armor.  That theme can be adapted in so many different ways from decorating their room to All Saints day's pageants.  It's great for a one word reminder to behavior:  shield, helmet, arrow, breastplate, girdle and the bow
