Maybe that wasn't really a can of worms. Interesting.
How about King Arthur? No, you're right. Not a lot of controversy there. But some really good books....
The Forever King by Molly Cochran and Warren Murphy
This was such an interesting read. King Arthur, Galahad and Merlin are all present and accounted for, though you may not recognize them at first! The Grail makes it's appearance too, with a very interesting history.
The pros-- fascinating treatment of all things Arthurian. All of the history of the Grail and everything was really cool. LOVED the treatment of Launcelot at the end. That guy just gets a bad rep. a lot.
The cons-- treatment of Christianity made me a little uncomfortable in places. Probably just me. Hal Woczniak is just not really a very likeable guy. Maybe that was part of the point, I don't know. Still, you just can't like him as much as you want to.
All in all, it was really good. I need to read the sequel now.
