of someone when there was danger. He wasn’t wrong, but she sympathized with Livvy’s desire to be
parabatai with Ty. To make sure her brother was always by her side.
“Got it!” Drusilla announced suddenly. She stood up from rummaging around in the map chest with
a long piece of parchment in her hands. Livvy, abandoning the parabatai discussion, hurried over to
help her carry it to the table.
In a clear bowl on the table’s center was a heap of sea glass the Blackthorns had collected over the
years—lumps of milky blue, green, copper, and red. Emma and Ty used the blue glass to weigh down
the edges of the ley line map.
Tavvy, now sitting on the edge of the table, had begun sorting the rest of the sea glass into piles by
color. Emma let him; she didn’t know how else to keep him distracted just now.
“Ley lines,” Emma said, running her index finger over the long black lines on the map. It was a map
of Los Angeles that probably dated back to the forties. Landmarks were visible under the ley lines:
the Crossroads of the World in Hollywood, the Bullocks building on Wilshire, the Angels Flight
railroad in Bunker Hill, the Santa Monica Pier, the never-changing curve of the coast and the ocean.
“All the bodies were left under the span of a ley line. But what Magnus said is that there are places
where all the ley lines converge.”
“What does that have to do with anything?” Livvy asked, practical as always.
“I don’t know, but I don’t think he would have said it if it didn’t matter. I imagine the place of
convergence has some pretty powerful magic.”
As Ty applied himself to the map with renewed vigor, Cristina came into the library and gestured
for Emma to come talk to her. Emma slid off the table and followed Cristina to the coffeemaker by the
window. It was witchlight powered, which meant there was always coffee, although the coffee wasn’t
always very good.
“Is Julian all right?” Emma asked. “And Mark?”
“They were talking when I left.” Cristina filled two cups with black coffee and dumped in sugar
from a small enamel pot on the windowsill. “Julian calmed him down.”
“Julian could calm anyone down.” Emma picked up the second cup of coffee, enjoying the warmth
against her skin, though she didn’t really like coffee and didn’t tend to drink it. Besides, her stomach
was tied in so many knots she didn’t think she could force anything down.
She walked back toward the table where the Blackthorns were arguing about the ley line map.
“Well, I can’t help it if it doesn’t make sense,” Ty was saying peevishly. “That’s where it says the
convergence is.”
“Where?” Emma asked, coming up behind him.
“Here.” Dru pointed at a circle Ty had sketched on the map in pencil. It was over the ocean, farther
out from Los Angeles than Catalina Island. “So much for anyone doing magic there.”
“Guess Magnus was just making conversation,” said Livvy.
“He probably didn’t know—” Emma began, and broke off as the library door opened.
It was Julian. He stepped into the room and then moved to the side, diffidently, like a conjuror
presenting the result of a trick.
Mark moved into the doorway after him. Julian must have gotten Mark’s old things out of the
storeroom. He was wearing jeans that were slightly short on him—probably a pair of his old ones—
and one of Julian’s T-shirts, heather gray and washed to a soft fadedness. In contrast, his hair looked
very blond, almost silvery. It hit his shoulders, looking slightly less tangled, as if he’d brushed the
twigs out of it at least.
“Hello,” he said.
