I've been reading this book called "Monster" by Jonathan Kellerman, I've been looking but found nothing, has their been a film based on this book? If so i'd bemost grateful if you could tell me :)
I don't know for sure if it's the adaptation of the book you've been reading, but there's recently been a film made called "Monster" about the life of Aileen Wuornos, the prostitute. It stars Charlize Theron (who won Best Actress at the Oscars for the role) and Christina Ricci.
Theron won her Oscar on Aileen's birthday, by the way.
