Sash Donnelly has done her best to move on – from Applegate, the small town where nothing ever seems out of the ordinary, and from that night, fifteen years ago.

Then it happens – the vicious murder that stuns Applegate’s tight-knit community. And Sash receives a phone call from Marcus, her childhood sweetheart. He’s facing a life behind bars and needs her to tell everyone the truth.

Lana, Sash’s sister, knows that something happened that night, something that changed Sash, but she has no idea what. And she has a secret too, one that could save Marcus’s life. Someone just needs to ask her the right question.


Proof is a perfect mix of crime and thriller, highlighting how one moment can determine the rest of your life
