There's a knock at the door. It's every mother's worst nightmare: the police are here. They tell me my beautiful daughter Charlotte has been hurt. They'll take me to the hospital, there's no time to lose… and I know this must be all my fault.

Charlotte and I argued so badly the last time we spoke. I was just worried about her, but she refused to hear me out. And now she's lying pale, still and silent in a hospital bed. I'm convinced this was no accident: the police should be questioning her boyfriend, Freddie.

I never thought he was good enough for her, but did he hurt my daughter? Guilt floods through me again and again. If we hadn't argued, she wouldn't have been with him today. If we hadn't argued, I could have been there for her. But I didn't listen and instead, she pushed me away. I didn't even know my darling girl was pregnant.

And now she's lost forever. The doctors say she will never wake up: the only part of her they can save is her unborn child…

There's only one thing I can do. He may be my grandchild's father, but I know Freddie is dangerous. I'll fight with everything I have to prove he's guilty.

I failed to protect Charlotte, but how far will I have to go to keep her baby safe? And will what's left of my family ever survive: or will my part in my daughter's death tear us all apart?
