Susan Tassone has written a number of works on the Poor Souls in Purgatory. I was sent one free after making a purchase from a Catholic bookshop on-line. It is a 30 day novena for the Poor Souls in Purgatory and the final day is a prayer called "the Heroic Act." In this prayer, one offers ALL our indulgences we receive here on earth to the Sacred Heart in order to allow His mother to free souls from Purgatory. I have been "re-dedicating" myself to this apostolate every day for over 3 years. The number of souls we release from Purgatory pray for us unceasingly. What a beautiful way to give of ones time here on earth! The Heroic Act is followed by a Litany and I repeat that nightly too.
