1. Death of the Borderer

The Queen 'neath the Hedge came from nowhere, from out of reed and nightshade. She conquered two worlds and entwined them together, Britain to the Other Realm - home of the mysterious Umbra.
Four hundred years after her death, every Britain is still mortally bonded to an Umbra. But now her treaty is unravelling and Georgian England's salons and ballrooms are haunted by a rumour:
'She's coming back.'
Everyone is trying to stop her, but there's a problem: no one knows who, or where, or what she is.
