In July I interviewed Michael Plekon about his forthcoming book Uncommon Prayer: Prayer in Everyday Experience. You may read that here. I also noted that I would post a reminder when the book was finally published in September, as it now has been.
Consider yourself reminded to go and buy a copy! While you're at it, check out some of his other books (or books devoted to him), all of which will be well worth your time.
In particular, I interviewed him in 2012 about Saints As They Really Are: Voices of Holiness in Our Time.
In an interview from 2011, we discussed some of his other earlier books, including Hidden Holiness as well as Living Icons: Persons of Faith in the Eastern Church.
He is also the editor of numerous works, including those by Afanasiev, Evdokimov, and others--don't forget the splendid biography of Elisabeth Behr-Siegel!
