John Ajvide Lindqvist's novel, a huge best seller in his native Sweden, is a unique and brilliant fusion of social novel and vampire legend. And a deeply moving fable about rejection, friendship and loyalty.

The international best seller and the book behind the film and play Let Me In.

Oskar and Eli. In very different ways, they were both victims. Which is why, against the odds, they became friends.

And how they came to depend on one another, for life itself.

Oskar is a 12-year-old boy living with his mother on a dreary housing estate at the city's edge. He dreams about his absentee father, gets bullied at school, and wets himself when he's frightened.

Eli is the young girl who moves in next door. She doesn't go to school and never leaves the flat by day. She is a 200-year-old vampire, forever frozen in childhood, and condemned to live on a diet of fresh blood.
