Nineteen-year-old Flora’s whole life changes when she discovers she is a Soul Keeper, and responsible for ensuring only pure souls are ever given a second chance on Earth.

This revelation means a move to the ancient Castle Dion, on the banks of the famous Loch Ness. A castle named after the team of shapeshifting warriors who are assigned to safeguard their Soul Keeper.

As Flora gets to know each of these protectors better, she quickly discovers her best friend Finlay has always wanted more than friendship.

Confusingly, Flora’s heart has other ideas. Ideas that mean she can’t keep her eyes off the brooding, dark-haired, Lyall.

But, the rogue souls that have been rejected by Flora have to go somewhere too, and the ruler of that world wants out so badly, he is prepared to invade the Soul Keeper’s dreams in a bid to break her mind.

Now, Flora and her Dion must be ready to face the threat of the Host of the Unforgiven Dead, as he tries to find a way to bring himself and his rogue souls to the mortal world!
