I‘m currently reading Which witch? by Eva Ibbotson.
The story is about the great dark wizard Arriman and how he starts a competition (or is convinced to) to find a suitable dark which to marry in order to sire the greatest dark wizard of all.
I remember reading it back in 1990 or something, and I remember liking it a lot. Reading it now, I understand that I probably didn’t catch the brilliance of it. I’m reading it in my native language and not in English, so I can’t exactly say anything about the quality of the translation, but so far it has had little footnotes about names and their meaning in English, just to tell the reader the significance of the names. Nice touch!
I would really recommend this as light reading for adults, and fun for kids too. At least for adults and kids like me…
