What is twilight besides a vampire book?

Whats twilight. I know its a book / movie but whats it about. I know vampires but what else??? Can you help me?

Bella (the main character) falls in love with the vampire, Edward. There are complications between the two because he has to keep himself from killing her (hes a vampire DUH) but it's an amazing series and my favorite.

the twilight seris is the best! omg I love all the books!

In twilight Bella(human) and Edward(vampire) fall in love, but its a hard relationship because with one wrong move he could easily kill her. he has a huge family and the rest are vampires too. no one esle knows bout them all being vampires but bella. I wont say any more cu z I dont want to spoile it. you have to read all the books
Twilight, New Moon, Eclipse, and Breaking Dawn
Then there is another book called Midnight Sun that hasnt come out yet but its the whole seris over but from Edwards point of view.
Plus there is another seris by the same author. theres only one book out right now in that seris and its called the Host.

um its a love story, if your on about the word its sumtime between sunset and sunrise I think, like there all to do with parts in the day twilight, new moon, eclipse, breaking dawn anyway did you see the new trailer omg I have to keep rewatching it , im from england at got up at 4am to see it air

its a sappy love story...but sooo sweet

Its not only about vampires. After the first book you are introduced to more characters who are other mystical creatures. The twilight saga is basically about Edward(vampire) who falls in love with a girl named Bella but has to restrain himself from killing her because of her scent and also has to risk his life protecting her while she is human. They are really good books full of love and action, I do reccomend reading them if you havent already
