Night's Sorceries

A recognized master fantasist, Tanith Lee has won multiple awards for her craft, including the British Fantasy Award, the World Fantasy Award for Life Achievement, and the Bram Stoker Award for Lifetime Achievement in Horror.
The final entry in Tanith Lee's classic fantasy series Tales from the Flat Earth, Night's Sorceries forms a breathtaking conclusion to a dark and intricate epic of demons, gods, and mortals.
Azhriaz, daughter of Azhrarn, Demon Lord of the Night, has defied her father's wishes. Taking on the mantle of Delirium's Mistress, she escapes her island prison in the Underearth, where she would have spent her life in eternal slumber. With Prince Chuz, her lover and the sworn enemy of Azhrarn, she flees to the mortal realm of the Flat Earth to escape her father's wrath.
But Azhrarn will not be so easily deterred, and the lovers' journey has not left the world untouched. In the wake of their flight, bizarre new enchantments emerge, exposing a world of chaos and mystery. The mortals of the Flat Earth are inextricably entwined in circumstances beyond their understanding, caught in the midst of grand conflicts of ambition and betrayal.
Night's Sorceries spins seven of these tales of wonder-of humans confronted with the supernatural. Trials of true love, tests of humility and fortitude, and startling transformations weave together in these lush stories of passion, revelation, and the human soul.
