A little late on this one, but Steven King says that Nora Roberts is cool. And who am I to argue with Steven King about cool?
But, it would also seem, that if you have been aware of the Nora Roberts cool before this official pronouncement, by having read many/most/all of her books (or even possibly owning a bobblehead) then, you too are cool. So, congratulations on being cool!
(And if that didn't make you cool - first, I'm so sorry, and second, check Steven King's list, maybe something else makes you cool.)
