Evagrius of Pontus, Talking Back: A Monastic Handbook for Combating Demons (Cistercian Studies Series) - an English translation of his Antirrhetikos
It's available in Kindle format but not Logos. [:(]
This is an important book in the history of Christianity, perhaps the very origin of the idea of the seven deadly sins. The Encyclopedia of Christianity says: "The seven vices can be traced back as far as Evagrius Ponticus (346–99), in his practical guides to the ascetic life of the desert anchorite."
