Set in a crumbling France. Told through aching hearts. The Darkest Oath is part historical fantasy, part gothic romance, and 100% unforgettable. I’m obsessed with this story of curses, rebellion, and love that outlives empires.
My Review:
I received an advance review copy for free, and I am leaving this review voluntarily.
I thoroughly enjoyed this book. This is the first book I’ve ever read by Lauren Lee Merewether. Her writing is exquisite. She sets the perfect tone for a this book, The Darkest Oath. The tone of her writing matches the time in which this book was set.
I love that this book is a longer read. As a reader, you get to get to know the characters and see them evolve into their entire selves. The characters just grow on you. I really love when I read a historical fiction novel and want to research the actual history of events.
The Darkest Oath ties in actual events, superstition, and love in an incredible way. This was a wonderful read. I recommend it. Enjoy the journey.
The Synopsis
Her love is his only salvation—and the undoing of everything he needed to survive.
An immortal knight. A fearless rebel. A love forged in the fires of revolutionary France.
Chevalier Rollant de Montvieux was once a man of honor. Betrayed on the battlefield and bound by a sorceress’s curse, he has spent six centuries serving the French crown—immortal, untouchable, and doomed to lose anyone he dares to embrace in love.
As revolution smolders in the streets of Paris, Rollant clings to duty as his only purpose in a wretched existence, until he meets her.
Élise has nothing left to lose. Defiant, outspoken, and determined to fight for freedom, she has no patience for kings or the royalists who serve them. But when she crosses paths with Rollant in a spy’s disguise, she senses something different beneath his quiet strength: a man burdened by secrets, trapped in a fate not of his choosing.
Drawn together by forces neither can control, their connection deepens in the shadows of a crumbling world.
But Rollant knows love is forbidden to him.
To hold Élise is to curse her to certain death.
As France teeters on the edge of war, Rollant must make an impossible choice: honor his unbreakable oath and protect her from afar—or risk everything, including her life, for one fleeting chance at love.
And Élise must decide where her true battle lies: in the streets of Paris, or in the arms of a man who may be her ruin—or her greatest salvation.

The Darkest Oath is a historical romance of sacred vows, haunted longing, and love that was never meant to survive, where curses and political unrest collide. A richly woven love story between a loyal immortal knight and a defiant rebel, this novel explores betrayal, legacy, and what it means to fight for the future when the past refuses to die.
This story is not high fantasy. There are no elaborate magic systems. Instead, magic exists like it did in medieval myth: whispered, elusive, and rooted in fear, not rules. It is mythic and enigmatic by design, woven more through atmosphere and consequence than explanation.
The curse is real.
The love is forbidden.
The oath… was only the beginning.
Take the oath. Choose the curse.
Step into a world where love is treason and every vow carries a price.
