Hi Mama-
I am 30. 2 years ago, the books rushed into the market because of the first movie. So I read the books after seeing the first movie. The movie does not really do the details of the books as much justice as it could, but at the same time, it is good. The gist of the story is that it is a love story.
Start with the Cullen Family. The father, aka the doctor, was a 16th century son of an anglican priest. He went out on a hunt after vampires and witches to please his father. He got bit and realised what was happening to him and because it was a supposed damnable thing and tried to end his life. He realised that he did not know how and took up with the royalty of his new species. He then decided that it wasn't what you were, but what you did with the cards you were dealt that made you who you were and decided never to feed on humans. Long story short, he became a doctor and studied for hundreds of years, always wanting to serve humanity. Skip forward to the 1900's and Edward is born. He ends up dying of the flu and his mother begs Doctor Cullen to save him, like she knows what he is and will give her son life. So he takes Edward as a son.Skip forward, Bella is born in the 80's, her mother and father split due to marital issues, her mother re-marries while she is in highschool and Bella goes to live with her dad in Washington so that her mom can freely travel with her baseball player husband.
Bella meets Edward and falls in love with him. Then it becomes the story of how do make an immortal and a mortal love last...can Bella be changed...is it the right thing to do? Will she lose her soul or be as the doctor believes, whatever she chooses- good or bad? And, will it violate the treaty with the wolves, protectors of humans who keeps human feeding vampires away....but the Cullens are an exception and have agreed to stay off the Wolves land.
It's a great story, but the books delve into Bella and Edward's married relationship, they do have sex but there are no details, and the struggle is to keep both Bella and Edward alive and well and to have that happily ever after that people love to read.
It is a little dark, and I am not sure that 8 years old is really old enough to read it. I would rent or borrow the movie when she is not home and watch it first. However, I think also that I would say not yet, but it is dependant on her maturity level. Avatar was a fantastic film, but the story stuck to a pure motivation to save a culture from the greed of another. Twilight, while I love it, is not really in the same category. Maybe you should read the books first, and read them with her....but beware of letting her grow up too soon. I say wait a few years. The buzz from the movies coming out will be over, but then you can purchase them all at once, discounted, and her maturity level will be a little higher. It's just not a kid story- it's an older teen story at a younger teen reading level, so an easy read. But beware the poularity and don't let it suck you in. Read it and see it first for yourself and then make your decision and stick to your guns.
I hope this helps. Good luck.
