Packed with enemies-to-lovers tension, heart-pounding action and devastating twists, the first book in The Nightfire Quartet is an epic vampire romantasy that begins with a slow burn and builds to a steamy love story. Zarya has always known she was dangerous. Raised from childhood as a prisoner, she's been trained to fight but forbidden from using her magic. When at last she breaks free, she flees, determined to learn why she was ever locked away. What she finds is a dazzling marble city on the brink of disaster, where demons prowl the streets every night. When she joins in the fight, desire sparks with a powerful commander, a blood-drinking immortal. But he's dangerous too, with secrets of his own. And if he knew Zarya's true self, he might turn against her in an instant. She knows she mustn't get distracted. She's only here to discover the truth. But since she arrived the demons have been growing bolder... Almost as if they're drawn to her presence. As Zarya unearths the mysteries of her captivity, she learns of an evil ancient magic that threatens to destroy everything. Soon, she faces an impossible choice: unleash her own magic and save her home, or lose herself to a darkness that has been waiting for her for centuries...
