A captivating dark gothic fantasy set in the same universe as the award-winning author's All The Murmuring Bones, The Path of Thorns and The Briar Book of the Dead. A tale of vampires, assassins, ancient witches and broken promises, perfect for readers of Alix E. Harrow, Hannah Whitten and Alexis Henderson.
Violet Zennor has had a peculiar upbringing. Training as a fighter in underground arenas, honing her skills against the worst scum, murderers and thieves her father could pit her against, she has learned to be ruthless. To kill. 
Until the day Hedrek Zennor dies. Violet thinks she’s free – then she learns that her father planned to send her into the Darklands, where the Leech Lords reign. Where Violet’s still-born brother was taken years ago. Violet steadfastly refuses. Until one night two assassins attempt to slaughter her – and it becomes clear: she’s going to have to clean up the mess her father made.
By turns gripping and bewitching, sharp and audacious, this mesmerising story takes you on a journey into the dark heart of Slatter's sinister and compelling fantasy world in a tale of vampires, assassins, ancient witches and broken promises.
