Slightly offtopic, but one of the strangest prayer books in contemporary language I have in my collection is called Praying With the Orthodox Tradition, which given it has a forward by Metropolitan Kallistos Ware, one would expect would be a typical Eastern Orthodox prayer book like the Jordanville Prayer Book etc, but it really isn’t at all. It consists of priests prayers from ancient liturgical texts found in Codex Barbarini 336 translated into modern English and rearranged as a series of short prayers, grouped for morning, evening, night and also the canonical hours, so there is some redundancy, and no guidance is provided on which one to say, nor are any of the usual acoutrements of an EO prayerbook present, like the Akathist, the prayers for preparation for Holy Communion, one or more canons, the Psalter (rare, but some have it), an abbreviated text of the liturgy of St. Chrysostom or an abbreviated form of the actual hours, etc.
I really like it however, as bizarre as it is, and it is unusual compared to the personal prayer books of pretty much every church.
