The Thunder of Justice provides messages from the major apparition sites in the world from the Blessed Mother. Messages include Church approved Guadalupe Mexico, Rue Du Bac France, LaSalette France, Lourdes France, Pontmain France, Fatima Portugal, Divine Mercy Sister Faustina, Beauraing Belgium, Our Lady of All Nations Amsterdam, Our Lady of America Ohio, Akita Japan, Kibeho Rwanda, San Nicholas Argentina, and many others. Major sites covered not approved by the church are Garabandal Spain, and Medjugorje Bosnia as well as many others.

Material presented is from the Third Secret of Fatima which clearly shows the Blessed Mother gave the very essence of the secret to her prophets because the Church suppressed it. The carnage we have seen in society and the church was prophesied in great detail. Also, there is no doubt John Paul II approved of Medjugorje, as well as Cardinals, Bishops and tens of thousand of priests worldwide. The book was never designed to be a definitive anthology of apparition sites, but deals with those that are considered the most significant in the Church.

Since the first edition was published in 1993, many sites and visionaries have been approved by the Church, which in many ways validates what was said earlier. Of particular interest is why the messages take place and what is said in that locale---and then seeing what was said and how it came true. An area many find most fascinating is the concept of the Warning and the Great Miracle prophesied at Garabandal Spain, where the Blessed Mother gave 2,000 messages to four young girls from 1961-1965. According to Garabandal, the Warning will take place at a time of great chaos in the world. It is designed by heaven to restore man to his senses where each and every person will see the state of their soul as God sees it at judgement.
