The biggest controversy of our time. Author removes the veil from the history of Aga Khani ismailis. After the publication of this book Aga Khan gave a farman to every single Ismaili paryer hall, not to support the author. Every Ismaili in the world knows about this author and his books and has been instructed not to support the books. A remote village in India or huge metropoliton city in USA, every Ismaili will have negetive feedback about the author and the book. Read it for yourself to see the truth. Every single aspect of the book makes sense if read with an open mind and for the purpose of research. Author gives examples from the work of Ismaili writters that current Imam is not the direct descendeant of Prophet Muhammad (PBUH) And ancestors of present Imam either practiced Sunni beliefs or Ithna Ishri practices.
