The newest title from Bibliotheca Alexandrina is Ascendant II, edited by Michael Hardy. It contains essays from several different authors, including John Beckett, Wayne Keysor, John Michael Greer, Brandon Hensley, and myself.
My article “Applying Cross-Cultural Methods of Myth Interpretation to the Myth of Baldr’s Death” is featured about halfway through the book. For anyone curious about why Loki’s involvement in Baldr’s death is actually essential to the maintenance of the cosmological order, I highly suggest reading that essay.
I actually highly suggest buying a copy of Ascendant II (and its precursor, Ascendant I) because it features polytheists discussing theology in the modern world. Theology is not often something discussed in Pagan and Polytheist circles, despite all the work we do with and for the gods.
