A perfect sunny day, a family celebration, a heart-stopping hour that changes everything... Dana has all she ever wanted - a husband she loves, her four-year-old daughter Kelsey who is the apple of her eye, and another baby on the way to complete her perfect family. But then the worst fear that Dana has, comes true, and everything she thought she knew, she now starts to doubt. As her world comes crashing around her, who can Dana trust? Her husband Logan who seems to be getting worryingly close to Dana's best friend Pippa? Her new friend Melanie who has a sinister habit of turning up in the strangest places? Her parents and her sister, who Dana knows are keeping a terrible secret from her? Matt, who says he's Dana's friend, but sometimes she's not so sure? Or will Dana discover that it's a dangerous mistake to trust anyone...
