Perfect for you if...

You love possessive alpha heroes who cross moral lines and aren't apologetic about it.
You're drawn to dark romance where the power dynamic is complicated and the chemistry is undeniable.
You read for the tension between surrender and resistance, not for a straightforward happily-ever-after.

Maybe not for you if...

You prefer heroes who are fundamentally good people or follow conventional moral codes.
You're looking for a gentle introduction to romance or anything that downplays the darker elements.
You want a standalone. This is book one of a series with ongoing plot threads.

About this book

Rowan King is a cold and ruthless commander of the armed forces. When he first encounters the narrator at her most vulnerable, he begins to exert control over her, rewarding obedience and demanding she earn forgiveness through difficult means. She experiences conflicting feelings about his treatment—simultaneously hating and desiring it. Escape is not possible for her. Rowan's intense desire for her breaks through her defenses, and he becomes her only protection in a dangerous world controlled by a secret society. He claims to protect what belongs to him, but the narrator questions whether his protection is worth its cost and whether her fragile heart can endure his powerful hold over her. This is the first book in the Devils & Pretty Sins series. It is a dark military romance featuring an unhinged, over-the-top hero.
