The Mark of Athena

was too late to write TEAM LEO on his shirt.

Sadly, the suits of armor were not as easily swayed as the Narcissus Fan Club had been.

The one with the wolf-headed helmet snarled, “I have been in your mind, Leo. I helped you start the war.”

Leo’s smile crumbled. He took a step back. “That was you?”

Now he understood why those tourists had bothered him right away, and why this thing’s voice sounded so familiar. He’d heard it in his mind.

“You made me fire the ballista?” Leo demanded. “You call that helping?”

“I know how you think,” said Wolf Head. “I know your limits. You are small and alone. You need friends to protect you. Without them, you are unable to withstand me. I vowed not to possess you again, but I can still kill you.”

The armored dudes stepped forward. The points of their swords hovered a few inches from Leo’s face.

Leo’s fear suddenly made way for a whole lot of anger. This eidolon in the wolf helmet had shamed him, controlled him, and made him attack New Rome. It had endangered his friends and botched their quest.

Leo glanced at the dormant spheres on the worktables. He considered his tool belt. He thought about the loft behind him—the area that looked like a sound booth. Presto: Operation Junk Pile was born.

“First: you don’t know me,” he told Wolf Head. “And second: Bye.”

He lunged for the stairs and bounded to the top. The suits of armor were scary, but they were not fast. As Leo suspected, the loft had doors on either side—folding metal gates. The operators would’ve wanted protection in case their creations went haywire…like now. Leo slammed both gates shut and summoned fire to his hands, fusing the locks.

The suits of armor closed in on either side. They rattled the gates, hacking at them with their swords.

“This is foolish,” said Lion Head. “You only delay your death.”

“Delaying death is one of my favorite hobbies.” Leo scanned his new home. Overlooking the workshop was a single table like a control board. It was crowded with junk, but most of it Leo dismissed immediately: a diagram for a human catapult that would never work; a strange black sword (Leo was no good with swords); a large bronze mirror (Leo’s reflection looked terrible); and a set of tools that someone had broken, either in frustration or clumsiness.

He focused on the main project. In the center of the table, someone had disassembled an Archimedes sphere. Gears, springs, levers, and rods were littered around it. All the bronze cables to the room below were connected to a metal plate under the sphere. Leo could sense the Celestial bronze running through the workshop like arteries from a heart—ready to conduct magical energy from this spot.

“One basketball to rule them all,” Leo muttered.

This sphere was a master regulator. He was standing at Ancient Roman mission control.

“Leo Valdez!” the spirit howled. “Open this gate or I will kill you!”

“A fair and generous offer!” Leo said, his eyes still on the sphere. “Just let me finish this. A last request, all right?”

That must have confused the spirits, because they momentarily stopped hacking at the bars.

Leo’s hands flew over the sphere, reassembling its missing pieces. Why did the stupid Romans have to take apart such a beautiful machine? They had killed Archimedes, stolen his stuff, then messed with a piece of equipment they could never understand. On the other hand, at least they’d had the sense to lock it away for two thousand years so that Leo could retrieve it.

The eidolons started pounding on the gates again.

“Who is it?” Leo called.

“Valdez!” Wolf Head bellowed.

“Valdez who?” Leo asked.

Eventually the eidolons would realize they couldn’t get in. Then, if Wolf Head truly knew Leo’s mind, he would decide there were other ways to force his cooperation. Leo had to work faster.

He connected the gears, got one wrong, and had to start again. Hephaestus’s Hand Grenades, this was hard!

Finally he got the last spring in place. The ham-fisted Romans had almost ruined the tension adjuster, but Leo pulled a set of watchmaker’s tools from his belt and did some final calibrations. Archimedes was a genius— assuming this thing actually worked.

He wound the starter coil. The gears began to turn. Leo closed the top of the sphere and studied its concentric circles—similar to the ones on the workshop door.

“Valdez!” Wolf Head pounded on the gate. “Our third comrade will kill your friends!”

Leo cursed under his breath. Our third comrade. He glanced down at the spindly- legged Taser ball that had knocked out Hazel and Frank. He had figured eidolon number three was hiding inside that thing. But Leo still had to deduce the right sequence to activate this control sphere.

“Yeah, okay,” he called. “You got me. Just…just a sec.”

“No more seconds!” Wolf Head shouted. “Open this gate now, or they die.”
