Just started the, apparently, award-winning "Jonathan Strange & Mr. Norrell" by Susanna Clarke. Promising, so far.
I was struck with a heavy feeling of recognition - due to my few attempts at the roleplaying game Ars Magica. Also focused on "true magic" and mythical, un-categorizable faery folk.
Set in the 1800s, it also reminded me of "The Baroque Cycle". Read this if you haven't!
