Pain is a great teacher.
I learned this lesson quickly.
The first punch landed hard against my ribs, knocking the air from my lungs. I gasped, staggering back, but the man in front of me didn't stop. Another blow—this time to my jaw. My vision blurred, my knees buckled, and I barely caught myself before hitting the mat.
"Again."
The voice was calm. Unyielding.
I spat blood onto the floor and looked up at the man towering over me. Kai Mercer. Ruthless. Precise. My new trainer and the closest thing to a devil in human form.
"This is pointless," I hissed. "I don't need to be a fighter. I just need to be smart."
Kai crouched in front of me, his expression unreadable. "Smart women still get killed, Celeste. You already know that."
I froze.
He wasn't wrong.
I had been smart before. I had played by the rules. And where had that gotten me? Lying in a pool of my own blood while the people I loved laughed over my corpse.
Never again.
With a growl, I pushed up from the floor and lunged.
Kai sidestepped easily, catching my wrist and twisting it behind my back in a painful hold. His breath was warm against my ear as he spoke.
"Use your rage. Control it. A wildfire burns everything, but a controlled flame? It destroys only what you want it to."
I clenched my jaw, forcing myself to breathe.
Control.
I needed control.
Kai released me, and this time, when I attacked, I was faster. Sharper. My movements were still sloppy, but I saw the faintest flicker of approval in his eyes before he knocked me flat on my back again.
"Better," he admitted. "But not good enough."
I wiped the blood from my lip and smirked. "Then we keep going."
Because I wasn't just training to fight.
I was training to win.
