Fire was hard enough to deal with. Infuse it with Hellfire and it was almost unstoppable.

So I didn’t even try to stop it.

Instead, I redirected it.

As the strike hurtled toward me, I lifted my staff in my right hand, whirling it back and forth in front of my body in a figure-eight spin and sent my will racing out through the staff, infused with soulfire to counter the Fallen angel’s Hellfire, shouting, “Ventas cyclis!”

A howling, whirling torrent of wind whipped out of my staff, spiraling tightly in on itself as the Hellfire reached it. There was a flash of light, a thunderous detonation, and the sharp scent of ozone as the two diametrically opposed energies met and warred. The spinning vortex of wind caught the violet fire and bent it up toward the distant ceiling of the vault, slewing back and forth, a gushing geyser of unearthly flame.

The effort to control that wind was tremendous, but even though the fire came within a few feet, the rush of air moving away from me prevented the thermal bloom from cooking me where I stood. My defense carried the entire power of the strike to the roof of the cavern, where it splashed and danced and rolled out in vast circular waves.

It was actually damned beautiful.

Ascher let out a short snarl of frustration as the last of the strike flashed upward. I released the wind spell but kept my staff spinning slowly, ready to counter a second time if I had to do it. Ascher had plenty of anger still raging in her, and she drew on it to gather more fire into her hands.

“Don’t do it, Hannah,” I called. “You aren’t going to beat me. You haven’t got what you need.”

“You cocky son of a bitch,” she said. “I’ve got everything I need to handle you, Warden. God, I was a fool to think you were any different than the rest of them.”

“Here’s the difference,” I said. “Back down. Walk away. I’ll let you.”

She actually let out a brief, incredulous laugh. “There is no end to the ego of the White Council, is there?” she asked. “You think you can pick and choose who is going to live and die. Decide all the rules that everyone else is going to live by.”

“The rules are there for a reason, Hannah,” I said. “And somewhere deep down, you know that. But this isn’t about the Laws of Magic or the White Council. It’s about you and me and whether or not you walk out of this vault alive.” I tried to soften my voice, to sound less frightened and angry. “That thing inside you is pushing your emotions. Manipulating you. She can show you illusions so real that you can’t tell the difference without resorting to your Sight. Did she tell you that?”

Ascher stared at me without saying anything. I wasn’t sure she’d heard me.

Hell. If Lasciel was inside Ascher’s head, twisting her perceptions with illusion right now, she might not have heard me.

“You can’t have had herCoin for long. A couple of weeks? A month? Am I right?”

“Don’t pretend you know me,” she spat.

“You’re right,” I said. “I don’t know you. But I know Lasciel. I had that Coin once upon a time. I had her inside my head for years. I know what she’s like, the way she can twist things.”

“She doesn’t,” Ascher said. “Not with me. She’s given me power, knowledge. She’s taught me more about magic in the last few weeks than any wizard did in my whole lifetime.”

I shook my head. “Fire magic is all about passion, Hannah. And I know you must have a lot of rage built up. But you’ve got to think your way past that. She hasn’t made you stronger. She’s just built up your anger to fuel your fire. Nothing comes free.”

Ascher let out a bitter laugh. “You’re scared, Dresden. Admit it. I’ve got access to power that makes me dangerous and you’re afraid of what I can do.”

And, right there, she showed me the fundamental difference between us.

I loved magic for its own sake. She didn’t.

The Art can be a lot of work, and it can sometimes be tedious, and sometimes even painful, but at the end of the day, I love it. I love the focus of it, the discipline, the balance. I love working with the energy and exploring what can be done with it. I love the gathering tension of a spell, and the almost painful clarity of focus required to concentrate that tension into an effect. I love the practice of it as well as the theory, the research, experimenting with new spells, teaching others about magic. I love laying down spells on my various pieces of magical gear, and most of all, I love it when I can use my talents to make a difference in the world, even when it’s only a small one.

Ascher . . . enjoyed blowing stuff up and burning things down. She was good at it. But she didn’t love her talent for the miracle it was.

She merely loved what she could do with it.

And that had led her here, to a place where she had tremendous power, but not the right frame of mind to understand the consequences and permutations of using it—or at least not where she needed it, deep in her bones. To wield power like she currently possessed, she needed to understand it on the level of gut instinct, having assimilated the Art so entirely that the whole reality of using it came to her without conscious thought.

It was why virtually every time she’d used magic in the past few days, it had been to destroy something, or else to protect her own hide from the immediate consequences of her own power. It was why she hadn’t put in the practice she needed to go up against someone with a broad range of skills. It was why she had focused exclusively on attacking me, to the neglect of her own defenses a few moments before. It was why she’d said yes to the Fallen angel who was now driving her emotions berserk.
