Lonely Becky spends her life on Chloe's social media, always on the outside looking in, until a sudden tragedy pulls her in deeper than she ever dreamed possible

Armed with her new alter ego Sasha, Becky makes herself indispensable to Livia. A party in Elliot's honour gives her the chance to get closer to Chloe's grief-stricken husband.

Becky begins investigating the secrets which Chloe kept from Elliot, Livia and the rest of the friends, but an unexpected run-in with Richard leads to a painful conclusion.

As she embraces life as Sasha, Becky loses herself in the luxurious world Chloe left behind, but she is forced to face the ghosts from her past at Phil’s art exhibition.

New information causes Becky to look at everything with fresh eyes as she tries to untangle the threads Chloe left behind, while increasingly at risk of being discovered.
