Reddit reviews The Apocrypha: Including Books from the Ethiopic Bible

Try this combination of books. The first is fantastic in terms of notes, references, etc., and is complete for Eastern Orthodoxy but not for Ethiopian, and has some material that the Ethiopians don't consider. The second should fill in the gaps with Ethiopian material - I don't know how good this version is and would have to rely on the reviews.

There is one single version in English but it is expensive and gets poor reviews.
