Best friends tell each other everything.

Or do they?

Georgia and Lydia are so close they're practically sisters.

So when Lydia starts an online business that struggles, Georgia wants to help her - but she also understands Lydia's not the kind to accept a handout.

But then Lydia starts confiding in her new internet buddy and Georgia discovers she doesn't know her quite as well as she thought.

Georgia knows she should reveal herself, but she's fascinated by this insight into her friend's true feelings.

Especially when Lydia starts talking about her.

Until Lydia reveals a secret that could not only end their friendship but also blow up Georgia's marriage.

Georgia's in too deep.

But what can she save?

Her marriage, her friendship - or just herself?
