I shot them both a cold glance — one look, unhurried, moving from her face to his and back again, cataloguing everything — and turned to leave. My heels were silent on the hardwood. I had learned to walk without sound in this house. I had learned to do many things without sound.

"Not so fast." Nico's voice was sharp, edged with something dark — the tone he used when he was about to make a decision that couldn't be walked back. "Don't think you're walking away from this, Rosalia."

I stopped. The hallway stretched ahead of me, dim and narrow, the soldier by the entrance shifting his weight almost imperceptibly, his hand drifting a half-inch closer to his waistband. I turned back slowly, meeting Nico's glare head-on.

"I'm going to make sure you regret ever betraying me," he continued.

Betray him.
