"This isn't a ghost we're dealing with. If only it were that simple..."

Eighteen years ago, when psychic Ruby Davis was a child, her mother - also a psychic - suffered a nervous breakdown. Ruby was never told why. "It won't help you to know," the only answer ever given. Fast forward to the present and Ruby is earning a living from her gift, running a high street consultancy - Psychic Surveys - specialising in domestic spiritual clearance.

Boasting a strong track record, business is booming. Dealing with spirits has become routine but there is more to the paranormal than even Ruby can imagine. Someone - something - stalks her, terrifying but also strangely familiar. Hiding in the shadows, it is fast becoming bolder and the only way to fight it is for the past to be revealed - no matter what the danger.

When you can see the light, you can see the darkness too.
And sometimes the darkness can see you.
