St. Faustina Prayer Book for the Conversion of Sinners

“Today bring to Me all mankind, especially all sinners, and immerse them in the ocean of My mercy.” — Jesus to St. Faustina

Throughout her Diary, St. Faustina speaks of Jesus’ call for the conversion of souls. Through prayer and sacrifice, the Lord calls us all to strive for our own conversion, and for the conversion of the whole world.
Perhaps you’ve tried everything to draw your friend or family member back to faith in God. In St. Faustina Prayer Book for the Conversion of Sinners, best-selling author Susan Tassone shows you how to place the lives of all you love into God’s merciful hands. Known worldwide as “the purgatory lady,” Susan invites you to learn how to live the message of conversion daily, to avoid purgatory, and to become more faithful in praying for others.


Catholic Exchange Interview with Fr. Edward Looney





       St. Faustina Prayer Book for the Conversion of Sinners is a much-needed treasure which allows us to glimpse the mercy of God and his call to conversion. I pray that all who read this book will be touched by God’s love and experience the grace needed to follow Jesus more closely as his disciples.

— Cardinal Seán P. O’Malley, OFM Cap.
Archbishop of Boston


       “In her most recent book, Susan Tassone – our very own ‘Apostle for the Souls in Purgatory’ – uses the spiritual wisdom of St. Faustina to call us all to conversion. Use it faithfully to pray for relatives and friends, and apply it to yourself to help with your own growth in holiness.”

— Greg Erlandson, Editor in Chief, Catholic News Service


       “Following her many valuable books on the holy souls in purgatory, Susan Tassone’s St. Faustina Prayer Book for the Conversion of Sinners involves three of my favorite topics: St. Faustina, mercy, and conversion. This is a great book to help you pray for others, but it’s more than that. Filled with prayers and inspiration for the continual, day-by-day conversion of our own hearts, it’s a book for each one of us.”

— Vinny Flynn, Author of Mercy’s Gaze


       “Each of us is called to become a saint. Once we hear the call of God, experience the pulsating love of the divine, and surrender every facet of our life and personality to the Lord, nothing can ever be the same again. Susan Tassone’s latest book, St. Faustina Prayer Book for the Conversion of Sinners, can greatly assist in the continual conversion of heart, mind, and soul needed to wholeheartedly respond to this universal call to holiness. The plethora of prayers, devotions, and spiritual practices this book contains can help the reader to obtain the graces needed for a deeper commitment to Christ for oneself, one’s loved ones and the entire world.”

— Most Rev. Donald J. Hying
Bishop of Gary, Indiana


       “In her—excellent—St. Faustina Prayer Book for the Conversion of Sinners, author Susan Tassone examines and explains the interdependence of all of us in God’s plan of salvation. How we play a role not only in our own conversion but in the conversion of others. As always, Susan never loses sight of the way this “vocation” includes praying for the holy souls in purgatory, just as Our Lady instructed the young children at Fatima in 1917. Charity was the essence of Mary’s message to them when she asked that they work for the conversion of sinners through prayer and sacrifice. It remains her message to us.”

— David M. Carollo
Executive Director
World Apostolate of Fatima


       “In the Gospel Our Lord instructs that some types of spiritual conversion can only be accomplished by prayer and fasting. Susan Tassone’s St. Faustina Prayer Book for the Conversion of Sinners provides us a wonderful resource to help focus one’s prayer to complement one’s fasting. I highly recommend it for those seriously wanting to ‘live the fast’ and convert hearts and souls to Christ!”

— Andrew LaVallee
Founder and Director of “Live the Fast”


       “In these secular times that relish personal autonomy as the rudder of life, we are tempted to relish and even boast about our sins. Concepts of conversion, mercy, penance, and forgiveness are hard to digest in this age. Susan Tassone offers a compendium here that brings forth from the Church’s treasury of prayers and self-examen contributions on these subjects by select saints with Sister Faustina Kowalska’s mystical intuitions as centerpiece. This work invites a contemporary generation to revisit the Church’s proclamation of the infinite mercy and love of Jesus Christ. With citations from the Marian appearances appealing for the conversion of souls, this book will assist the pious soul to explore more deeply the freeing experience of conversion and an encounter with the mercy of God that can penetrate the cynicism of the age and draw the soul closer to the person of Jesus Christ.”

— Most Reverend Joseph N. Perry
Auxiliary Bishop
Archdiocese of Chicago


       “Once again Susan Tassone has taken the Diary of St. Faustina and culled gems that could be overlooked by even an expert on this saint’s spirituality. (When St. Faustina tells of her efforts to effect a change in her sister, Wanda, I think of all the people for whom I’ve ever prayed.) Susan’s superior writings on St. Faustina’s spirituality can help us each grow in holiness as we attempt to become a channel of God’s Mercy for others.”

— Father Dan Cambra, M.I.C.
Holy Souls Sodality at The National Shrine of The Divine Mercy


       Susan Tassone’s St. Faustina Prayer Book for the Conversion of Sinners is a must read! It not only will inspire you but renew your faith in the unfathomable mercy of God. Do yourself a favor: read this book, share it with others, and trust in the power of God’s mercy to bring about conversion even of the most hardened heart.”
