A lost loch

Toby, widowed and adrift, is certain of only one thing: as a child she visited a drowned village, filled with precious treasures. Haunted by this impossible memory, she ventures deep into the Scottish Highlands on a quest to find what has been lost.

A secret house

Ash is consumed with grief after the death of her mother until she stumbles into the mysterious Half-Way House. Here, she finds herself a caretaker of the Mirror Halls: the shadowy realm between the sleeping and the dead. As she learns to walk amongst the Dreamers, she begins to suspect that her discovery of the Halls - and the secrets they conceal - was no accident.

As the two women embark on their separate journeys to the truth, they soon find themselves entangled in a mystery far darker and deeper than either could have imagined.
