I'm pretty sure that it never says, but you find out in Breaking Dawn, the only time that she's mentioned, that she died in a car crash.
It was not discussed in the book.
if u are meaning Jacob black out of twilight he actually has 2 sisters, rachael and rebecca and his mum died in a car crash so he lives with his dad, billy black
Quillete Tribe
Because he was in an accident.
I think it is Jacobs sister Rachel.
Jacobs dad
Jacksonville, Florida
in twilight? they didnt die. they joined Jacobs pack.
Rebecca Black is actually mentioned in the book 'Twilight'. AND BREAKING DAWN
her name in the book is Sarah
If you mean Esme it is Elizabeth Recer.
