Neversuch House is home to the very unusual Halibut family. Spanning generations, the Halibuts all live together totally isolated from the outside world, never needing - or wanting - to step outside the walls of Neversuch, with every whim being catered for by a mass of servants.

For the House is steeped in secrets, secrets that some people want to remain hidden, and, as Omnia tries to unravel the mysteries of Neversuch House, someone is watching her, and they will do anything to stop her from revealing the truth...
