What happens to the charecter after the book?

I was sort of disappointed at the ending of "Bec". All the main characters died except for the mentally retarded boy, Bran. Bran's only friends are all dead and he is the only survivor from his village. I think bran is going to either die because he was badly injured at the end of the book or he will be very lonely for the rest of his life if he does survive.
