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 Lydia's not the kind to accept a handout.

Setting up a fake Twitter account, Georgia hopes to give her friend some anonymous moral support by posing as a potential customer. 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 the truth - especially when Lydia starts talking about her - but she just can't help herself.

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? 'I loved Worst Idea Ever. Another Fallonesque treat, possibly my favourite so far.
