I Am Morgan Le Fay is a young adult novel which tries to give Morgan Le Fay more of a reason for her actions and more psychological depth. It’s reasonably successful in that, though it’s not one of my favourite Arthurian stories I’ve ever read — it seems a bit slight, and Morgan’s behaviour and the outcome was entirely obvious. The mythology is a bit of a hotchpotch, but I didn’t mind that too much because it was so lightly touched on. Cernunnos is a character, but it doesn’t really go into the significance of magic and how that’s linked to divinity in their world.
I kind of think I might be able to judge this better once I’ve read I Am Mordred as well, to see how Springer handles Mordred. Mary Stewart manages to excuse Mordred everything while throwing the blame on Morgan, and there’s always blame to go around in Arthurian stories, so I’d kind of like to see where it shifts in this case. Presumably not to Mordred, but to whom?
