Well, as with you and Cherryh, the answer is "Of course I have! But somehow the formatting got messed up."

I had even gone through the list, counting as I went, and come up with 30 read, and then counted my bolds here and counted 29. But a quick run through didn't identify the one I'd missed. So thanks for the catch, fixed now.

(I read Wrinkle, A Wind in the Door, and A Swiftly Tilting Planet but never got around to Many Waters or any of her other books.)
