“Betrothals can be broken, alliances reforged. He might be persuaded to see you as king if” – she traced a finger down my chest – “you could be persuaded to take a new wife.”

Revulsion held me frozen in place even as my mind recoiled from what she was suggesting. She had to be sick, her brain warped by iron-madness or worse. No amount of ambition could drive anyone toward this. “You are insane.” I choked the words out before stepping out of reach. “What sort of twisted creature are you to want such a match?”

The smile slowly melted from her face. “You were not opposed to it so very long ago.”

Enough of this. “With Anaïs, perhaps, but not with you.” With clawed fingers of magic, I tore the mask off her face, sending her staggering. “Never with you.”

Regaining her balance, she snapped her head up to look at me, teeth bared with the fury of a rabid animal. The air in the room went searing hot, the vases and lamps shattering under the pressure. The whole wing of the palace shook and trembled beneath my feet, sending books toppling off their shelves and knocking paintings from the walls.

Instead of trying to stop her, I laughed in my sister’s face. “What do you suppose Father will do to you if you kill me?”

The shaking stopped and Lessa’s face resumed a false expression of composure. “I don’t want you dead.”

“Liar.”

She huffed out a breath and rolled her eyes. “Is that how it’s to be? Because I can lie you’ll not believe a single word I say?”

“No,” I said. “I’ll not believe a thing you say because I don’t trust you.”

The room began to cool before she answered.

“Believe me or not, it’s the truth. I don’t want you dead, I want you to see reason.” She lifted a foot as though she intended to walk closer, then wisely lowered it again. “Don’t you see? United, we could have everything. Together, we could kill Father, and believing his daughter would become queen, Angoulême would support you over Roland. And if he doesn’t?” She shrugged one slender shoulder. “We kill him. Kill Roland, too, because of a certainty, Trollus is better off without our younger brother. Together, no one would be able to stand against us. No one would dare contest our power.”

“You are my sister!” And no logic, or reason, or promise of power could undo that fact.

“No one need ever know that.”

My whole body went rigid, the warmth of the room doing nothing to chase away the icy prickles of revulsion sweeping my skin. “I’d know!” I screamed the words into her face. “You’d know!”

She didn’t even flinch. “If this is about Cécile, be assured that I wouldn’t care if you brought her back to Trollus and kept her as your mistress. You’d still be bonded to her, after all. Ours would be primarily a political arrangement.”

I could see in her eyes that she didn’t care. Even if such a match did disgust her, Lessa was more than capable of pushing such feelings aside in her pursuit of power. Or worse, maybe she wasn’t even disgusted by the idea at all. All she wanted was to be queen. It was the only thing that mattered.
