It's not connected to your Lent, but I did just buy Words For Our Time: The Spiritual Words of Matthew the Poor, a new book that compiles the sayings of the modern Coptic Orthodox monk of the same name (d. 2006; head of the Monastery of St. Macarius and father of confession of HH Pope Shenouda III in the 1950s), translated from some of his Arabic sources. I dunno how interested you are in monastics and their words, but he is one of the modern fathers who has had a wide appeal and impact outside of our church, probably thanks to the Eastern Orthodox publishers who published some of his books in English (The Orthodox Prayer Life). I know several Eastern Orthodox who admire him, so I'm assuming he's a good fit for Chalcedonians and non-Chalcedonians alike.
I also just got Grillmeier and Hainthaler's Christ In the Christian Tradition Vol. 2, Pt. 4: The Church of Alexandria with Nubia and Ethiopia After 451 and Minassian's A History of the Armenian Holy Apostolic Orthodox Church in the United States (1888-1944), but I have a feeling these kinds of dense, academic tomes (Minassian's history was his Ph.D. dissertation, published posthumously after many years of trying to do so) probably won't see much use during Lent. God and me willing, I will focus on resuming and strengthening regular prayer with the Agpeya (Coptic book of the hours, which we use year around to structure our daily prayers), intercessory prayers to my father and baptismal saint St. Shenouda the Archimandrite and Abba John the Little (two saints I feel especially close to) and the other desert fathers who are our models of repentance and ascetic striving, and so forth.
Do Roman Catholics use their Book of the Hours for private prayer? I did attend occasionally the public prayer of the hours when I was RC, but I don't remember it being used privately. Maybe if there is a way to do that, it might benefit you guys during your Lent.
