The Power of the Rosary is a book on Catholic themes by Reverend Albert J. M. Shamon. The book revolves around the topic of Catholic beliefs on the power of prayer via the rosary. It builds on the fifteen rosary promises and extends the discussion to the present day. It discusses the fact that the rosary has been featured prominently in the context of several Marian apparitions such as those in Međugorje and Our Lady of Fatima. It also recounts many anectodal incidents regarding the rosary, ranging from religious and political prisoners in China to every day Catholics.
