Fantasy is often characterized by magic, mythical creatures, and the forces of good triumphing over evil, but this isn't always the case. Plenty of dark fantasy books are so gruesome and grim that they could be considered part of the horror genre as well. This doesn't mean that the story won't end somewhat happily for the characters, but it does mean that more gore and difficult situations will be described than in a typical fantasy novel. Additionally, the tension and stakes hold a creepy sensation of terror and foreboding that are impossible to escape.

Grimdark and horror-esque works aren't the best fantasy book series for beginners, as they can be emotionally difficult to read because of the intense subject matter. However, for readers who are more interested in horror and haven't explored speculative fiction in-depth, these novels are great transitory materials that might pique their interest. While every narrative must have conflict and darkness in order for it to be compelling, some are so scary that the villains and events of the projects would give anyone nightmares.

10 Fairy Tale (2022)

Written by Stephen King

Many underrated Stephen King books need adaptations, and this recent fantastical addition to his oeuvre fits the bill.

However, this land is full of danger and turmoil, and Charlie is put into terrifying situations and eventually takes it upon himself to rescue the kingdom of devastation.

King has often imbued his horror works with elements of sci-fi and fantasy, and this has only added to the chilling atmosphere he's fostered in his writing. At this point in his career, King is well-established, so he can experiment even more with form and genre, stepping further into fantasy than he has in the past.

7 The Last Tale Of The Flower Bride (2023)

Written by Roshani Chokshi

While gothic and horror elements often go hand-in-hand, The Last Tale of the Flower Bride leans more into its gothic influences, which characterizes how the aspects of fear populate the story. The Last Tale of the Flower Bride uses more subtle build-up and increasing tension to make the reader afraid rather than overt gore and jump scares. Romance, mystery, and family secrets flesh out the world of Indigo and her new husband as they're forced to take an unexpected journey into Indigo's past.

Roshani Chokshi is better known for her children's literature, with The Last Tale of the Flower Bride being her first foray into adult fiction. However, Chokshi proves that she's more than capable of weaving a tale that connects with older audiences, as the central relationship between Indigo and her husband is enormously compelling. Additionally, The Last Tale of the Flower Bride shines the most in its visual descriptions and the lurking ghosts of the past that haunt the reader and characters.

Written by Krystal Sutherland

Iris, the main character in House of Hollow, knows that her childhood contains a secret, but she and her sisters have never unpacked what happened to them.

5 Gallant (2022)

Written by V.E. Schwab

V.E. Schwab has written many great works of contemporary fantasy, and her style has always leaned toward the mysterious and dangerous within her story's imagined worlds. Though Gallant isn't her most popular book, it's one of the most unique and blends horror elements into its narrative seamlessly. Olivia Prior returns to her family home, the titular Gallant, after many years to find that the place calls to her, but not everything is as it seems. There's a hidden world in the shadows of Gallant that Olivia can access, but it's no sanctuary.

Gallant is one of Schwab's YA books, so while there are still plenty of spooky themes, the plot doesn't go too far in scaring Olivia or the audience. Olivia is mute, which is an exciting representation within the YA fantasy genre, and her journey to discover who she is and understand what happened to her family is relatable. Her world is filled with shadowy ghouls who she can always see, but the scariest part of the series is undoubtedly the villain who attempts to control both Gallant and Olivia.

4 House Of Leaves (2000)

Written by Mark Z. Danielewski

The complex and genre-bending House of Leaves incorporates elements of academic writing, film criticism, and horror fantasy into a work that needs to be read to be fully understood. Most of the novel is told from the perspective of the narrator, Johnny Truant, who is editing a manuscript a deceased man wrote about a documentary that Truant believes doesn't exist. Within the documentary, a family encounters a maze that appears within their house that's infinite and leads to nowhere, trapping one of them inside and leading to the deaths of others.

The truth of the house's maze and the dangers within it are up to the interpretation of the reader, but they remain vividly engaging and well crafted.

There are several stories within the story in House of Leaves that can be difficult to keep track of, especially since none of the multiple perspectives are reliable narrators or experts in their field. However, this makes reading House of Leaves an exciting challenge for the reader to piece together the information Mark S. Danielewski provides and uncover why certain aspects of the story are withheld. The truth of the house's maze and the dangers within it are up to the interpretation of the reader, but they remain vividly engaging and well crafted.

3 The Godblind Trilogy (2017–2019)

Written by Anna Stephens

Beginning with Godblind, the trilogy by Anna Stephens follows the story of Rillirin, a young woman who escapes servitude from the Mireces. They are a sect that worships ancient and evil Red Gods and plans to invade the central land of Rilpor. However, Rilliran isn't the only strong character in the Godblind novels, as the story is populated by excellent characters who work through their trauma, grapple with their faith, and grow as people throughout the narrative. While Godblind is labeled as a Grimdark fantasy most often, plenty of moments can be considered horror.

The Godblind Trilogy doesn't hold back when it comes to descriptions of violence and assault, making the fantasy series quite dark. Reading the Godblind books can be emotionally devastating, but the novels include great LGBTQ+ representation and expand upon the narrative with each installment. The sequels, Darksoul and Bloodchild, increase the action and incredible world-building that Stephens begins in Godblind and conclude the series in unexpected but satisfying ways. Stephens isn't afraid to put the characters and reader through the wringer in each installment of the story.

2 The Prince Of Nothing Series (2003–2006)

Written by R. Scott Baker

All three books in The Prince of Nothing Series illustrate what R. Scott Baker does best, which is to imbue high fantasy writing with niche elements of darkness and horror. There are clear connections to great sci-fi and fantasy works like Dune and The Lord of the Rings within The Prince of Nothing books. The character, Anasûrimbor Kellhus, is a prophesized leader with incredible abilities who may not be the messiah his people were hoping for. Though most of the characters within the story are human, there are gods, monsters, and aliens who flesh out the world.

While the story takes place in another world, there are many comparisons to be drawn between the events of the books and the warring factions who try to destroy each other and real life.

Kellhus' teacher, Drusas Achamian, comes to worry that he shouldn't have imparted his knowledge to the young man and that fate might have other plans for him. While the story takes place in another world, there are many comparisons to be drawn between the events of the books and the warring factions who try to destroy each other and real life. Much of the darkness and violence that are described in The Prince of Nothing is similar to historical events and reflects both the goodness and evil that humanity is capable of.
