It's about a girl called Bella Swan who lives in Arizona and her mum remarries and Bella decides to move to Forks to live with her dad. When at school she meets a boy called Edward Cullen.
Who seems to be very nice and good at everything but is hiding his true identity. When Bella finds out that he's a "blood sucking demon" she doesn't realise she's putting herself and the people she loves in danger....
I love all of the Twilight books; New Moon, Eclipse and Breaking Dawn. If you haven't read them yet READ THEM!
