I'll definitely have to look up that Walton later on. Though i had some problems with certain aspects of her retelling of the Mabinogion (then again, I have certain problems with the Mabinogion itself here and there
) there were other things about it liked quite a lot. I also enjoyed her novel, Witch House
, though I felt the final portion was a bit of a let-down (too explanatory, dissipating the atmosphere).
I do see a one-volume edition of her Mabinogion novels around a fair amount, so she's either currently or print or at least was so quite recently.
White... It has been quite a long time since I read this, and I never owned a copy of the original versions (though I have read them, back in my teens -- and I definitely prefer the originals in many ways). A somewhat neglected writer, at least by most fantasy fans, these days, and undeservedly so, I think.
(Didn't Lin include the sorcerous battle between Merlin and Mim in one of his anthologies? Kingdoms of Sorcery
or Realms of Wizardry
, if memory serves. That was one of the things which went when he did the revision, if I'm not misremembering....)
