About The Book

From the acclaimed author of The First Sister series, an epic fantasy set in a realm where gods devour each other to fuel their power, following a crew of unlikely allies on a desperate quest to stop the god of War from conquering the known world.

Years ago, the god of War took everything from aging mercenary Mordrena Halfheart—her homeland, her family, her god, even her magic. So when offered a place in the coalition of mages who aim to kill the War, she digs her nails and teeth into the chance at revenge. But the War is not the only god whose path is intertwined with Halfheart’s. Another has been lurking in her shadow for years, desperate to manipulate her fate to serve his own purpose.

As Halfheart and her unlikely allies journey to find the one weapon that might turn the tides of the War’s unrelenting conquest, long-buried secrets are revealed, loyalties tested, and the fate of the known world is left hanging in the balance.

An exploration of loss, grief, and power, Halfheart is a wild, soulful, structurally inventive, and immersive standalone that proves Lewis understands the epic fantasy genre just as well as they do space opera.

Raves and Reviews

"Halfheart is a mind-bending epic of a book with its bombastic action, visceral worldbuilding, and narrative devices that leave you constantly on edge about everything you're being told. Every character shines and intrigues, particularly its protagonist Mordrena, an aging but battle-hardened mercenary who's equal parts tough as nails and heartbreakingly vulnerable. One of the greatest storytellers of our generation, Linden A. Lewis blows me away every time."

Xiran Jay Zhao, #1 New York Times bestselling author of Iron Widow

"I loved Halfheart's mix of genuine grief, anger and emotion clashing against these nigh-insurmountable mythic forces that warp and dominate the setting. Sublime in every sense of the word."

Gareth Hanrahan, author of The Dungeon Book

"Visceral, vulnerable, and beautifully crafted, Halfheart is the kind of richly-imagined fantasy that makes writers long to write and readers yearn for more. Lewis's razor-sharp prose cuts to the heart of grief and explores just how immeasurably love and loss transform us. An incomparable standalone."

Linsey Miller, author of That Devil, Ambition
