she took a pale column of silvery-white stone from the inside of her jacket pocket. She flushed
slightly, aware of Julian’s eyes on her as he realized what she was holding: an unnamed seraph blade.
“What is he going to do with adamas?” Julian demanded.
“Adamas that has been treated by the Iron Sisters goes for a high price at the Shadow Market,” said
Rook, not taking his eyes off Emma’s prize. “But it still depends on what you want to know about.”
“The Midnight Theater and the Followers,” Emma said. “We want to know about them.”
Rook narrowed his eyes. “What do you want to know?”
Emma gave him a brief rundown of the events of the night before, leaving out Mark and how they’d
found out about the Lottery in the first place. When she was done, Rook whistled.
“Casper Sterling,” he said. “I always thought that guy was a scumbag. Yakking on about how he
was better than werewolves, better than humans, too. Can’t say I’m sorry his number came up.”
“Johnny,” Emma said severely. “They’re going to kill him.”
An odd expression flickered across Rook’s face, but it vanished quickly. “And you want me to do
what about it? They’re a whole organization, Carstairs.”
“We need to know who their leader is,” said Julian. “Belinda called him the Guardian. He’s the
one we need to find.”
“I don’t know,” said Rook. “I’m not sure pissing off the Followers is worth even adamas.” But his
eyes clung to the silvery-white stuff longingly. Emma pressed the advantage.
“They’ll never know you had anything to do with it,” she said. “But I saw you flirting with Belinda
at the Shadow Market. She’s got to know.”
Rook shook his head. “She doesn’t.”
“Huh,” Emma said. “Okay, which of them does?”
“None of them. The leader’s identity is totally secret. I don’t even know if it’s a man or a woman.
The Guardian could be either, you know?”
“If I find out you’re hiding something you know from me, Johnny,” Emma said in a cold voice,
“there will be consequences. Diana knows I’m here. You won’t be able to get me in trouble with the
Clave. But I could get you in trouble. Serious trouble.”
“Emma, forget it,” Julian said in a bored voice. “He doesn’t know anything. Let’s take the adamas
and go.”
“They get two days,” Rook said in a thin, angry voice. “When their numbers get picked. They get
two days before the kill has to happen.” He glared at them both, as if somehow this was their fault.
“It’s sympathetic magic. The energy of the death of a supernatural creature powers the spell that
makes them all stronger. And the leader—he shows up for the kill. That much I know. If you’re there
for the death, you’ll see him. Or her. Whoever it is.”
“The Guardian shows up at the murder?” Emma said. “To harvest the energy?”
“So if we shadow Sterling, if we wait for someone to attack him, we’ll see the Guardian?” Julian
said.
“Yeah. That should work. I mean, you’re crazy to want to be there at some big dark-magic party,
but I guess it’s your business.”
“I guess it is,” Julian said. His phone buzzed again. LIVVY WON’T TELL ME ANYTHING. SHE’S LOCKED
HERSELF IN HER ROOM. HELP.
A tendril of worry uncurled in Julian’s stomach. He told himself he was being stupid. He knew he
worried about his siblings too much. Ty had probably wandered off after an animal, was petting a
squirrel or cuddling a stray cat. Or he might have shut himself away with a book, not wanting to
socialize.
