So here's the chellenge:
Mini Challenge Question 1:
What is your favorite type of myth (Greek, Roman, Egyptian etc)?
As a scholar in Latin, I have a deep and abiding love for the Greco-Roman mythos so that will always be my first choice. However, I've always been intrigued by far-eastern cultures, although I know next to nothing about them. Also, I found Celtic and Norse mythology through reading and I love it.
Mini Challenge Question 2:
What is your favorite book with some type of mythology in it?
Difficult question, there are so many, some with made up in-world mythologies and some drawing from known traditions.
Interpreting the question as "known traditions", I think I'd have to go with a series, The Fionovar Tapestry. It takes together all of the main mythologies into a "master" world where all myths and legends originates and is the richest and most complex exploration of mythologies I've yet seen.
Edit: Of course, made from scratch mythologies goes to Terry Pratchett. Obvs. If I were a Discworld goddess, I'd BE Annoia.
UPDATE: I'm done with Dead Reckoning and it turns out that Impulse is written in verse and was a quick read. I'm on page one of Paranormalcy now - can't wait to read it!
