She doesn’t remember her past. He might be the key to it.

Eira Eckhart has spent years building a quiet life in a small town at the edge of a recently overthrown kingdom. Her memory is fractured, her past a blur—but with her shop, her loyal rabbit familiar, and practicing only the potions magic still legal under the watchful eye of the Iron Empire, she’s managed to remain unnoticed by the empire’s witch hunters.

Until Hugo Venton walks through her door.

Brash, clever, and infuriatingly handsome, Hugo is searching for something…and seems to know more about Eira than she knows about herself. But when a terrifying encounter with an unnatural, deadly new breed of soldier puts a price on her head, she has no choice but to join Hugo on his quest.

Their hunt for a missing princess pulls Eira across the continent—and deeper into a past she can’t recall. As buried memories, mysteries in the Iron Empire’s capital, forgotten feelings, and the truth behind her identity begin to surface, Eira realizes the forbidden magic simmering in her veins might be the very thing that could save them from the Iron Empire’s forces as they draw ever closer…if she can remember how to control it in time.

She doesn’t remember her past. But some memories will come with a cost.
