Everyone is lying But the dead know the truth

A week-long grief retreat on a beautiful country estate with no phones and no wifi isn't ex-tarot reader Blue's usual getaway. But ever since her mother's death she's been carrying a secret. Could this finally help her let it go?

When she arrives, it's raining, and there's something strange about the house. Only a few guests have made it through the weather. As the owners, Molly and Joshua Park, try desperately to cling to normality, the storm worsens until they're stranded in the house - cut off from the outside world.

And after one of the guests disappears in the night, Blue wonders who around her, the Parks and the guests, is telling the truth about why they're there - and whose grief might be hiding a deeper secret.

The flood water rises. Everyone is keeping secrets - but only one is a killer. Can Blue escape with her life, and her sanity?
