Medjugorje Complete: The Definitive Account of the Visions and Visionaries looks at the alleged visions of the Blessed Virgin Mary at Medjugorje, their origins, and their impact on the Catholic Church. It is an expanded, revised, and updated version of two previous works, Understanding Medjugorje and Medjugorje Revisited, published in 2006 and 2011 respectively.

Medjugorje Complete focuses on the transcripts of the original tapes of the visionaries made in June 1981. It also looks at the credibility of the visions and the visionaries, demonstrating serious problems in accepting Medjugorje as genuine. It also examines the role of theologians and the Hercegovina Franciscans in promoting Medjugorje, and its tangled historical and religious background, as well as its links with the Charismatic Renewal. In sum, it examines all the relevant evidence about Medjugorje, and concludes that, despite some "good fruits," it does not appear to be genuinely supernatural. If you want to know the truth about Medjugorje, then-forty years after the story began-Medjugorje Complete offers the definitive account.
