Changes made for the TV version from the Books........
I read all the books a few years ago......but:
Wasn't Grace's husband DEAD in the books? Now he's living with a woman in a nice house and has tons of money??
Eric? Was he even mentioned in the books? I don't remember him at all.
He reminds me of a character in the books. Olivia's Mother marries a man and he has a son just like Eric. Kind of a shiftless/loser who always makes excuses. It seems like the decided to give Jack that son and not Olivia's step-father.
