 clearly. They bear no relation to your enemies on the other side of the world." 

"You breed mutants here," Caius spit back at him. 

Edward's jaw clenched and unclenched, then he answered evenly, "They aren't even werewolves. Aro can tell you all about it if you don't believe me." 

Not werewolves? I shot a mystified look at Jacob. He lifted his huge shoulders and let them drop �a shrug. He didn't know what Edward was talking about, either. 

"Dear Caius, I would have warned you not to press this point if you had told me your thoughts," Aro murmured. "Though the creatures think of themselves as werewolves, they are not. The more accurate name for them would be shape-shifters. The choice of a wolf form was purely chance. It could have been a bear or a hawk or a panther when the first change was made. These creatures truly have nothing to do with the Children of the Moon. They have merely inherited this skill from their fathers. It's genetic �they do not continue their species by infecting others the way true werewolves do." 

Caius glared at Aro with irritation and something more �an accusation of betrayal, maybe. 

"They know our secret," he said flatly. 

Edward looked about to answer this accusation, but Aro spoke faster. "They are creatures of our supernatural world, brother. Perhaps even more dependent upon secrecy than we are; they can hardly expose us. Carefully, Caius. Specious allegations get us nowhere." 

Caius took a deep breath and nodded. They exchanged a long, significant glance. 

I thought I understood the instruction behind Aro's careful wording. False charges weren't helping convince the watching witnesses on either side; Aro was cautioning Caius to move on to the next strategy. I wondered if the reason behind the apparent strain between the two ancients �Caius's unwillingness to share his thoughts with a touch�was that Caius didn't care about the show as much as Aro did. If the coming slaughter was so much more essential to Caius than an untarnished reputation. 

"I want to talk to the informant," Caius announced abruptly, and turned his glare on Irina. 

Irina wasn't paying attention to Caius and Aro's conversation; her face was twisted in agony, her eyes locked on her sisters, lined up to die. It was clear on her face that she knew now her accusation had been totally false. 

"Irina," Caius barked, unhappy to have to address her. 

She looked up, startled and instantly afraid. 

Caius snapped his fingers. 

Hesitantly, she moved from the fringes of the Volturi formation to stand in front of Caius again. 

"So you appear to have been quite mistaken in your allegations," Caius began. 

Tanya and Kate leaned forward anxiously. 

"I'm sorry," Irina whispered. "I should have made sure of what I was seeing. But I had no idea___" She gestured 

helplessly in our direction. 

"Dear Caius, could you expect her to have guessed in an instant something so strange and impossible?" Aro asked. "Any of us would have made the same assumption." 

Caius flicked his fingers at Aro to silence him. 

"We all know you made a mistake," he said brusquely. "I meant to speak of your motivations." 

Irina waited nervously for him to continue, and then repeated, "My motivations?" 

"Yes, for coming to spy on them in the first place." 

Irina flinched at the word spy. 

"You were unhappy with the Cullens, were you not?" 

She turned her miserable eyes to Carlisle's face. "I was," she admitted. 

"Because... ?" Caius prompted. 

"Because the werewolves killed my friend," she whispered. "And the Cullens wouldn't stand aside to let me avenge him." 

"The shape-shifters," Aro corrected quietly. 

"So the Cullens sided with the shape-shifters against our own kind �against the friend of a friend, even," Caius summarized. 

I heard Edward make a disgusted sound under his breath. Caius was ticking down his list, looking for an accusation that would stick. 

Irina's shoulders stiffened. "That's how I saw it." 

Caius waited again and then prompted, "If you'd like to make a formal complaint against the shape-shifters �and the Cullens for supporting their actions�now would be the time." He smiled a tiny cruel smile, waiting for Irina to give him his next excuse. 

Maybe Caius didn't understand real families �relationships based on love rather than just the love of power. Maybe he overestimated the potency of vengeance. 

Irina's jaw jerked up, her shoulders squared. 

"No, I have no complaint against the wolves, or the Cullens. You came here today to destroy an immortal child. No immortal child exists. This was my mistake, and I take full responsibility for it. But the Cullens are innocent, and you have no reason to still be here. I'm so sorry," she said to us, and then she turned her face toward the Volturi witnesses. "There was no crime. There's no valid reason for you to continue here." 

Caius raised his hand as she spoke, and in it was a strange metal object, carved and ornate. 

This was a signal. The response was so fast that we all stared in stunned disbelief while it happened. Before there was time to react, it was over. 

Three of the Volturi soldiers leaped forward, and Irina was completely obscured by their gray cloaks. In the same instant, a horrible metallic screeching ripped through the clearing. Caius slithered into the center of the gray melee, and the shocking squealing sound exploded into a startling upward shower of sparks and tongues of flame. The soldiers leaped back from the sudden inferno, immediately retaking their places in the guard's perfectly straight line. 

Caius stood alone beside the blazing remains of Irina, the metal object in his hand still throwing a thick jet of flame into the pyre. 

With a small clicking sound, the fire shooting from Caius's hand disappeared. A gasp rippled through the mass of witnesses behind the Volturi. 

We were too aghast to make any noise at all. It was one thing to know that death was coming with fierce, unstoppable speed; it was another thing to watch it happen. 

Caius smiled coldly. "Now she has taken full responsibility for her actions." 

His eyes flashed to our front line, touching swiftly on Tanya's and Kate's frozen forms. 

In that second I understood that Caius had never underestimated the ties of a true family. This was the ploy. He had not wanted Irina's complaint; he had wanted her defiance. His excuse to destroy her, to ignite the violence that filled the air like a thick, combustible mist. He had thrown a match. 

The strained peace of this summit already teetered more precariously than an elephant on a tightrope. Once the fight began, there would be no way to stop it. It would only escalate until one side was entirely extinct. Our side. Caius knew this. 

So did Edward. 

"Stop them!" Edward cried out, jumping to grab Tanya's arm as she lurched forward toward the smiling Caius with a maddened cry of pure rage. She couldn't shake Edward off before Carlisle had his arms locked around her waist. 

"It's too late to help her," he reasoned urgently as she struggled. "Don't give him what he wants!" 

Kate was harder to contain. Shrieking wordlessly like Tanya, she broke into the first stride of the attack that would end with everyone's death. Rosalie was closest to her, but before Rose could clinch her in a headlock, Kate shocked her so violently that Rose crumpled to the ground. Emmett caught Kate's arm and threw her down, then staggered back, his knees giving out. Kate rolled to her feet, and it looked like no one could stop her. 

Garrett flung himself at her, knocking her to the ground again. He bound his arms around hers, locking his hands around his own wrists. I saw his body spasm as she shocked him. His eyes rolled back in his head, but his hold did not break. 

"Zafrina," Edward shouted. 

Kate's eyes went blank and her screams turned to moans. Tanya stopped struggling. 

"Give me my sight back," Tanya hissed. 

Desperately, but with all the delicacy I could manage, I pulled my shield even tighter against the sparks of my friends, peeling it back carefully from Kate while trying to keep it around Garrett, making it a thin skin between them. 

And then Garrett was in command of himself again, holding Kate to the snow. 

"If I let you up, will you knock me down again, Katie?" he whispered. 

She snarled in response, still thrashing blindly. 

"Listen to me, Tanya, Kate," Carlisle said in a low but intense whisper. "Vengeance doesn't help her now. Irina wouldn't want you to waste your lives this way. Think about what you're doing. If you attack them, we all die." 

Tanya's shoulders hunched with grief, and she leaned into Carlisle for support. Kate was finally still. Carlisle and 

Garrett continued to console the sisters with words too urgent to sound like comfort. 

And my attention returned to the weight of the stares that pressed down on our moment of chaos. From the corners of my eyes, I could see that Edward and everyone else besides Carlisle and Garrett were on their guard again as well. 

The heaviest glare came from Caius, staring with enraged disbelief at Kate and Garrett in the snow. Aro was watching the same two, incredulity the strongest emotion on his face. He knew what Kate could do. He had felt her potency through Edward's memories. 

Did he understand what was happening now �did he see that my shield had grown in strength and subtlety far beyond what Edward knew me to be capable of? Or did he think Garrett had learned his own form of immunity? 

The Volturi guard no longer stood at disciplined attention �they were crouched forward, waiting to spring the counterstrike the moment we attacked. 

Behind them, forty-three witnesses watched with very different expressions than the ones they'd worn entering the clearing. Confusion had turned to suspicion. The lightning-fast destruction of Irina had shaken t
