Angels: Our Elder Brethren by (the recently sainted) Nicholai Velimirovic, Bishop of Zica. This is a lengthy exposition, citing scripture extensively. But unlike many religious angel pages, which feel like nature guides, this one is deeper. It ends by calling "from this valley of tears" for their prayers on our behalf.
Angels: Blessed Messengers of God by Bishop Alexender, Holy Trinity Orthodox Mission, La Canada, CA. Includes an addendum by Steven Bushnell on "Counterfeit Angels":
"Nearly all these books fail to consider that the devil and his legions of demons are fallen angels who can disguise themselves as angels of light to cause the destruction of our souls."
The World of the Angels reprinted from "Orthodox Russia" (1999). Three-part report gets into the major topics, including demons, and with the attention to celestial hierarchies characteristic of Orthodox pages. Covers functions of less-commonly venerated angels, like Jegudiel and Barachiel.

The Heavenly Host in Coptic Tradition by Otto Meinardu, Coptic Church Review (2000). A scholar reviews the evidence for a non-scholarly audience. In recent years there have been a number of apparitions of Michael, held in high regard generally. As Meinardu writes:
"These manifestations ought to be seen in the light of the present precarious situation of members of a beleaguered minority. Wholeheartedly they trust in the words of the prophecy that 'all that time the archangel Michael shall arise and deliver his people from all trouble' (Dan. 12: 1, 2)."
