Perfect for you if...

You love gothic fantasy with a morally grey protagonist and don't mind your heroines dangerous and unpredictable.
You're drawn to slow-burn romance between flawed characters with genuine chemistry and high stakes.
You want lush, atmospheric prose that makes you feel the mist and shadow of the world.

Maybe not for you if...

You prefer straightforward heroes who are clearly good and don't wrestle with the darkness inside them.
You need romance to be the central plot rather than woven through a larger magical quest.
You dislike unreliable narrators or protagonists whose grip on reality becomes questionable.

About this book

Elspeth Spindle lives in an eerie, mist-locked kingdom where she relies on the Nightmare—an ancient, mercurial spirit trapped in her head—to protect her and keep her secrets. When she meets a mysterious highwayman on the forest road, her life changes drastically. She discovers he is the King's nephew and Captain of the Destriers, wanted for high treason. Elspeth joins him on a dangerous quest to cure the kingdom of dark magic infecting it. Together, they have until Solstice to gather twelve Providence Cards, which are the keys to the cure. As their attraction intensifies and the stakes grow higher, Elspeth confronts a darker truth: the Nightmare is slowly taking over her mind, and she may not be able to stop him.
