Well, 'The Graveyard Book' by Neil Gaiman is a great dark fantasy story for younger audiences but still has that dark edge. It's about a boy raised in a graveyard. 'His Dark Materials' by Philip Pullman is another notable one. It has a complex cosmology and deals with themes like good and evil, free will, and the nature of the soul. And there's 'The Name of the Wind' by Patrick Rothfuss. It's a beautifully written story with elements of magic, adventure, and a fair amount of darkness.
One of the best is 'The Sandman' by Neil Gaiman. It weaves a complex tapestry of dreams, nightmares, and the supernatural. Another great one is 'American Gods' also by Gaiman, which explores the idea of old gods living in modern America. And then there's 'A Song of Ice and Fire' by George R. R. Martin. It has a richly detailed world filled with political intrigue, magic, and dark elements.
Some excellent dark fantasy stories include 'The Kingkiller Chronicle' by Patrick Rothfuss. The story of Kvothe is full of mystery, magic, and a touch of the macabre. 'The Lies of Locke Lamora' by Scott Lynch is also a great pick. It's set in a fictional city and follows a group of thieves with a lot of dark and unexpected twists. And don't forget 'The First Law' trilogy by Joe Abercrombie. It has a gritty and often cruel world with morally ambiguous characters.
