I've been on a Meg Cabot kick recently, when one of my colleagues overheard me saying this, she corrected my pronunciation of the author's name. I had been saying it with a "silent T," Meg Cabot, to rhyme with... Bordeaux, I guess. It turns out that it's actually Meg Cabot, to rhyme with habit. I confirmed the pronunciation by double-checking with one of my favorite sites ever, The Author Name Pronunciation Guide put together by TeachingBooks.net. I must get in the "habit" of saying, "Meg CaboT"
Checkout the site, if you haven't already... it's a fantastic collection of audio clips of authors explaining how to pronounce their own names. Now you'll never have to stumble over the names of Louis Sachar, Jon Scieszka or Susan Patron (hint: it's not like library patron) again.
