It's been eight years since Gen Loxley lost her daughter, Beth.

Since that day, Gen has been floundering. While her husband Art builds his business reputation and their fortune, she can't let go of Beth.

And then one day, everything changes. A strange woman shows up on Gen's doorstep, saying the very thing she longs to hear: that Beth is alive. That she is out there somewhere, waiting for Gen to find her...

It's insane. Unthinkable. But why would someone make up such a story? Ignoring the warnings of her husband and friends, Gen begins to hope - hope that quickly turns into fear and paranoia.

With questions swirling around her head, Gen is determined to uncover the truth. But who can she trust? Why is Art so reluctant to get involved? To save his wife from further hurt? Or something much more sinister? Is Beth even really out there? And, if so, who is responsible for taking her?

What is the truth about Beth Loxley?
