When their parents return, they will find Olivia's bed empty. Their eldest daughter gone. Never to return.

Until now.

But is the woman who claims to be Olivia really all she seems? And is everything Caitlin said she saw that night really the whole truth?

Their family have dreamt of this moment. But could Olivia's return be what destroys them...
