Julie Law

Livia married into House Vantorra with a single goal: to be the power behind the throne. But her husband, Marcus, proved a failure as heir, and his brother, Titus, was a cruel idiot. With those two as her heirs, Empress Aurelia started seeking a new wife, someone who could bear her an heir she could trust with the empire. Once she knew that, Livia made a desperate, forbidden gamble. She offered herself to her mother-in-law. What began as a cold bargain for power quickly spiraled into a feverish obsession.
In Aurelia's private chambers, Livia discovered a woman of absolute dominance with an appetite that left her undone. It didn't take long for her to become the Empress's creature, bound to a woman who demanded total surrender in every sense of the word.
