I am reading 2000 edition of A Prodigal Saint: Father John of Kronstadt & the Russian People by Professor Nadieszda Kizenko published by The Pennsylvannia State Universdity Press.
Prof. Kizenko is the daughter of a prominent ROCOR priest and a professor of Russian history. The book is based on her doctoral thesis.
This book could only have been written by the child of a priest who has first-hand knowledge a parish priest's life. She is objective and a true scholar while at the same time an Orthodox Christian conscious of the Orthodox tradition.
She was the first person writing on the topic who had access to a wealth of archival souces, including Fr. John's personal notebooks/ diaries from the time he was a seminary student. She compares for example the hagiography written about Fr. John by ROCOR sources and the liturgical expressions such as tropars etc. to hagiography written by the ROC-MP after the fall of communisim and their liturgical hymns etc.
She also handles difficult topics such as Rasputin and why the Russian royal family did not call upon Fr. John. How Fr. John was discussed in the contemporary press and how he was one of three popular figures at the time: Tolstoy, Chaikovsky and himself.
An excellent book which I am still reading but would recommend.
