Festus

I've started reading Festus by Philip James Bailey, and so far I'm really enjoying it.

It's a conversation between Festus and Lucifer, and although it's supposed to be based on Catholicism it seems (to me) to have much more in common with the Bhagavad Gita.

It's in the public domain, but is still hard to find online.  I've only found it at Standard Ebooks, HERE. but they offer it in several different formats.
