Case in point:
I am currently listening to book 3, Blameless, in the Parasol Protectorate series. Light, frothy, amusing paranormal suspense/romance set in Victoria England. Perfect fare when life is a little... heavy.
There is a character in these books called Lord Akildama. (Since I am listening to the audiobook, that spelling is my guess and may bear no resemblance to its actual spelling in the book.) In books 1 and 2, Soulless and Changeless, this is pronounced Lord Ah-kill-DAH-mah. But in book 3 -- same narrator, mind you -- it becomes Lord Ah-KEEL-dah-mah. Annoying, but oh, well.
Imagine my astonishment when suddenly in the middle of book 3 the name become Lord Ah-kill-DAH-mah once more. WTF? How will it be pronounced in book 4, Lord Ab-ber-CROHM-bee?
And that is what has set my teeth on edge today. I knew y'all wanted to know.
