I did a quick check and found this beautiful video to watch on YouTube:
It's basically a reading of the first part of True Devotion, with Catholic artwork
scrolling by. The lady reading has excellent diction and dramatic expression. She
evokes remarkable comprehension. A joy to hear and see!

Considered the greatest single book on Mary ever written, this classic shows the way to Jesus through Mary. It sums up the entire Christian life and provides the key both to sanctity and to salvation. Beloved by countless souls; makes lasting devotees. St. Louis De Montfort prophesied that True Devotion to Mary would be the way of life of the great Saints of the latter times. This devotion is destined to change the world!
De Maria numquam satis! Ad Iesum per MariamSt. Louis-Marie Grignion de Montfort wrote the Treatise on
True Devotion to the Blessed Virgin at the beginning of the 1700s, but the manuscript remained practically unknown for more than a century. When, almost by chance, it was at last discovered in 1842 and published in 1843, the work was an instant success, proving extraordinarily effective in spreading the “true devotion” to the Most Holy Virgin.
It came to light eventually that St. Louis-Marie had known by private revelation that his book would be hidden from the world for a long time, and then would become widely known in the age when it would be most needed. Therefore, its erstwhile seclusion was a fulfillment of that foreknowledge the Saint had experienced.
As I recall hearing, the original, handwritten pages were stored in a travel trunk and stashed in someone's storage area or attic, then a century later, they were found by people who had not been alive at the time of the writing or first packing away. It is a lot like the story of the music of Johann Sebastian Bach, which was mostly forgotten for many years until rediscovered later. And the story of Mother Mariana de Jesus Torres, of Our Lady of Good Success, whose life and teachings were stored away and forgotten for over 3 centuries, only to be found and made known at the end of the 20th century, just as it had been foretold by Our Lady.
