From Wikipedia:
Mäṣḥafä Kedus (Holy Scriptures) is the name for the religious literature. The language of the writings is Ge'ez. The holiest book is the Orit (from Aramaic "Oraita" – "Torah") which consists of the Five Books of Moses and the books Joshua, Judges and Ruth. The rest of the Bible has secondary importance. Sources are lacking on whether the Book of Lamentations is excluded from the canon, or whether it forms part of the Book of Jeremiah as it does in the Orthodox Tewahedo biblical canon.[citation needed]
Deuterocanonical books that also make up part of the canon are Sirach, Judith, Esdras 1 and 2, Meqabyan, Jubilees, Baruch 1 and 4, Tobit, Enoch and the testaments of Abraham, Isaac and Jacob.
Non-Biblical writings Include: Nagara Muse (The Conversation of Moses), Mota Aaron (Death of Aharon), Mota Muse (Death of Moses), Te'ezaza Sanbat (Precepts of Sabbath), Arde'et (Students), Gorgorios, Mäṣḥafä Sa'atat (Book of Hours), Abba Elias (Father Elija), Mäṣḥafä Mäla'əkt (Book of Angels), Mäṣḥafä Kahan (Book of Priest), Dərsanä Abrəham Wäsara Bägabs (Homily on Abraham and Sarah in Egypt), Gadla Sosna (The Acts of Susanna) and Baqadāmi Gabra Egzi'abḥēr (In the Beginning God Created). Zëna Ayhud (Jews Story) and fālasfā (Philosophers) are two books that are not holy but still have a great influence.

Have these books all been translated into English? If so, where can I find them?
