Epic fantasy featuring warrior priestesses and fickle gods at war

Hessa is an Eangi: a warrior priestess of the Goddess of War, with the power to turn an enemy's bones to dust with a scream. Banished for disobeying her goddess's command to murder a traveller, she prays for forgiveness alone on a mountainside.

While she is gone, raiders raze her village and obliterate the Eangi priesthood. Grieving and alone, Hessa - the last Eangi - must find the traveller and atone for her weakness and secure her place with her loved ones in the High Halls. As clans from the north and legionaries from the south tear through her homeland, slaughtering everyone in their path Hessa strives to win back her goddess' favour.

Beset by zealot soldiers, deceitful gods, and newly-awakened demons at every turn, Hessa burns her path towards redemption and revenge. But her journey reveals a harrowing truth: the gods are dying and the High Halls of the afterlife are fading. Soon Hessa's trust in her goddess weakens with every unheeded prayer.

Thrust into a battle between the gods of the Old World and the New, Hessa realizes there is far more on the line than securing a life beyond her own death. Bigger, older powers slumber beneath the surface of her world. And they're about to wake up.

Available in print, ebook and audiobook formats, wherever books are sold.


‘Fantasy fans won’t want to skip H.M. Long’s epic Viking-inspired debut, which is packed with action and stars an unforgettable protagonist’

- Bookbub Best of 2021

"Hall of Smoke is a breath of fresh air. The world is unique, the fights are top-notch, and the cast is unforgettable. A dazzling, fast-paced story with clashing civilizations, squabbling gods, and an indomitable heroine caught in the center of it all, Hessa's is a tale that will grab you from the very first line and won't let you go. I can't wait to see what Long comes up with next."

Genevieve Gornichec, author of The Witch's Heart


"Long gives us a flawed hero, a woman battling grief, rage and – perhaps most poignant of all – doubt. It is thrilling to stand beside Hessa as she stares into the abyss and begins to reassemble herself there. Long's writing is elegantly understated, filling out Hessa's complex world without ever stranding us – we are with her through every stumble and triumph. Hall of Smoke is ultimately a book about what it means to have your deepest illusions shattered and still scrape together the courage to begin again. A vivid and compelling debut."
Lucy Holland, author of Sistersong

"Hessa is a brilliantly written heroine, and I could easily have spent another 400 pages with her. The book's world-building is intricate and refreshingly original, and it all ramps up to a finale that is the dictionary definition of epic."
Allison Epstein, author of A Tip for the Hangman

‘Long refuses to play it safe and, in the process, brings something new to the epic fantasy genre’ - Beauty in Ruins

Temple of No God

A companion novel to Hall of Smoke, and the second book in the planned Four Pillars quartet.

After a brutal war between the gods, Hessa—High Priestess of the Eangen—has brokered a fragile peace. Through great sacrifice, she has forged an alliance between warring tribes and introduced her people to the true god.

But a new threat is growing across the southern border.


In the remnants of the once-great Arpa Empire, three factions are vying for the imperial throne, and the vast well of raw magical power only accessible to the Arpa Emperor. Already beating back former Arpa legionaries at her borders, Hessa knows she cannot let this chance slip by. She must intervene, for the safety of her people.

With the peace she has sacrificed so much for at stake, Hessa must venture into the heart of enemy territory, where warring Arpa factions are not the only danger she must face. A sinister new cult is on the rise, one with the power to absorb the life of everything it touches. With enemies on every side and her fragile alliance beginning to waver, Hessa must decide who to trust—no matter what it may cost her…

Barrow of Winter

Goodreads badge icon reading "add to goodreads"

Set in the world of Hall of Smoke and third in the overall timeline of The Four Pillars series, this stand-alone title follows Thray, daughter of Ogam.


Thray is the Last Daughter of Winter, half immortal and haunted by the legacy of her blood. When offered a chance to visit the northern land of Duamel, where her father once ruled, she can't refuse – even if it means lying to the priesthood she serves and the man she loves.

In Duamel, Thray’s demi-god siblings rule under the northern lights, worshipped by arcane cults. An endless winter night cloaks the land, giving rise to strange beasts, terrible storms and a growing, desperate hunger. The people of Duamel teeter on the edge of violence, and Thray’s siblings, powerful and deathless, stand with them on the brink.

To earn her siblings’ trust and find the answers she seeks, Thray will have to weather assassinations, conspiracies and icy wastelands. And as her siblings turn their gaze towards the warmer, brighter land she calls home, she must harness her own feral power and decide where her loyalties lie.

Because when the spring winds blow and the ice breaks up, the sons and daughters of Winter will bring her homeland to its knees.

Barrow of Winter is available in print, ebook and audiobook formats.


"A beautiful, impressionistic, and engrossing tale that is reminiscent of a Mercedes Lackey title. It is a coming-of-age tale full of danger and adventure, set against an icy, winter backdrop that imbues itself into each sentence."
-Library Journal


"An intricate world tapestry with colorful threads of myth and magic...Readers will want to stick with this stalwart heroine through her chilly treks and blood-stained battles." 

-Publishers Weekly 

“An epic fantasy set in a rich and wintry world of warriors, gods and monsters, with epic battles, dangerous magic, and complex family bonds. Thray is a heroine both powerful and vulnerable, and I loved her journey.”
Sue Lynn Tan, bestselling author of Daughter of the Moon Goddess

“Brimming with magic and intrigue, Barrow of Winter is a spellbinding read. Thray’s northern quest had me turning pages late into the night, as did Long’s beautiful winter-sharp prose. A vivid story that lingers long after the last word.”
Rebecca Ross, internationally bestselling author of A River Enchanted

"A world so vividly rendered you'll feel the ice on the pages"
Richard Swan, Sunday Times bestselling author of The Justice of Kings
“Long's story of a woman caught between the mortal and mythical worlds is evocative, lyrical, and brimming with fierce magic. Another brilliant addition to this clever, Norse-inspired series.”

The fourth and final book in the Four Pillars series, Pillar of Ash is slated for release January 16th, 2024.

Yske, a healer and daughter of the warrior priestess Hessa, holds the balance of power in a world-shattering war of the gods, in this thrilling, mythical and emotional epic fantasy saga.

The enthralling conclusion to the HALL OF SMOKE saga, perfect for fans of Ragnarok, Claire LeGrand, Margaret Owen, V. E. Schwab and Melissa Caruso.

Yske, daughter of the legendary warrior priestess Hessa, has dedicated her life to medicine and pacifism in service to Aita, the Great Healer. When her twin brother Berin, hungry for glory, gathers a party to investigate rumors of strange sightings in the Unmade - shadows in the darkness at the end of the world - Yske joins the mission, to keep him safe.

Their journey east takes them through primal forests, walking paths last trod when gods were at war and ancient, powerful beasts were defeated and bound. And the closer they get to the Unmade, the more strange and terrible things haunt them from the shadows, corruptions in nature and monstrous creatures of moss and bone.

Earning the respect of Berin and his warriors, Yske must forge a place for mercy and healing in a world of violence and sacrifice. She must survive murderous ambushes and brutal sieges and take her place at the center of the oldest war of all.

Thrust into a desperate conflict of survival, Yske and Berin will wage the final war with the gods - in the shadow of a vast and ancient tree, the fate of creation is about to be decided.

"A tale that deserves to rank alongside RJ Barker's The Bone Ships and Robin Hobb's The Liveship Traders in the top rank of maritime fantasy."
Anthony Ryan, internationally bestselling author of

Blood Song, The Wolf’s Call and more

The first book in a new swashbuckling high-seas adventure series, with a dark folktale twist.

Mary Firth is a Stormsinger: a woman whose voice can still hurricanes and shatter armadas. Faced with servitude to a deathless pirate lord, Mary offers her skills to his arch-rival in exchange for protection - and, more importantly, his help in sending the pirate to a watery grave.

But Mary's dreams are dark and full of ghistings, spectral creatures who inhabit the ancient forests of her homeland and the figureheads of ships. Her new ally has his own vendetta, complete with revenge and a lost fleet, locked in the eternal ice of the far north, and disgraced pirate hunter Samuel Rosser is close on their trail. Samuel will stop at nothing to restore his good name and claim the only thing that stands between himself and madness: a talisman stolen by Mary herself.

Finally, driven into the eternal ice at the limits of their world, Mary and Samuel must choose their loyalties and battle forces older and more powerful than the pirates who would make them slaves.

Long's Dark Water Daughter is a deftly executed and highly entertaining combination of high seas adventure and flintlock fantasy, enriched by a duo of engaging leads and an original take on magic.

Thrust into a mission of intrigue and infiltration, they seek to break into the most secure prison on the Mereish Coast. But as they sail deep into enemy territory they find themselves hunted by a cunning and mysterious new foe. An enemy who seems to know their every secret, and who will kill to keep their own.

As the Black Tide rises, and fleets take to the water, Sam, Mary and Benedict are on a desperate race for survival – both their own, and the free nations of the Winter Sea.

The Entwined Duology


Coming March 11th, 2025 from Titan Books

Three sisters join the hunt for a stolen magical artifact in the start of this Gilded Age fantasy duology. Perfect for fans of heists, skullduggery and stolen kisses, and authors such as Nghi Vo and M. A. Carrick.

Ottilie Rushforth hides from the mighty Sorcerer's Guild as secretary to a has-been detective. She is Entwined – threads of magic run beneath her skin, and the Guild would trap her in service.
But Ottilie has a plan to escape the Guild forever with her estranged fiancé, the enigmatic poet, soldier and smuggler Lewis Illing. All she must do is track down a mysterious artifact, claim the bounty, and leave the city forever.


But Ottilie's sisters – Pretoria, a quick-witted sorceress and thief, recently emerged from exile - and Madge – a guild mage to the core – appear to make equally unwelcome offers. A new life at the cost of everything she has ever wanted, or prestige and safety in a gilded cage.

With her life on the line, Ottilie must track down the artifact in a city torn apart by prejudice and violence, and choose between the two sides of herself – the fugitive and the Entwined.
