The perfect night.

I had been so excited for our big New Year's Eve party. Hosting with my best friend Alice and our two beautiful boys - my Leo and her Robbie, who had grown up together like brothers.

A shocking death.

But then I heard the terrible crash. I remember the flashing lights of the ambulance and how everyone then turned on Leo. Saying that Robbie was dead because of my son.

Who is to blame?

The boys had argued, but Leo still won't tell me why. I know he's keeping a secret from me. I need to find out the truth, need to clear the name of my darling boy before something terrible happens to him, too.

But I also need to make sure no one finds out the truth about me...
