“
Bob,” she said, “offerings burned in the mortal world appear on this altar, right?” Bob frowned uncomfortably, like he wasn’t ready for a pop quiz. “Yes?” “So what happens if I burn something on the altar here?” “Uh…” “That’s all right,” Annabeth said. “You don’t know. Nobody knows, because it’s never been done.” There was a chance, she thought, just the slimmest chance that an offering burned on this altar might appear at Camp Half-Blood. Doubtful, but if it did work… “Annabeth?” Percy said again. “You’re planning something. You’ve got that I’m-planning-something look.” “I don’t have an I’m-planning-something look.” “Yeah, you totally do. Your eyebrows knit and your lips press together and—” “Do you have a pen?” she asked him. “You’re kidding, right?” He brought out Riptide. “Yes, but can you actually write with it?” “I—I don’t know,” he admitted. “Never tried.” He uncapped the pen. As usual, it sprang into a full-sized sword. Annabeth had watched him do this hundreds of times. Normally when he fought, Percy simply discarded the cap. It always appeared in his pocket later, as needed. When he touched the cap to the point of the sword, it would turn back into a ballpoint pen. “What if you touch the cap to the other end of the sword?” Annabeth said. “Like where you’d put the cap if you were actually going to write with the pen.” “Uh…” Percy looked doubtful, but he touched the cap to the hilt of the sword. Riptide shrank back into a ballpoint pen, but now the writing point was exposed. “May I?” Annabeth plucked it from his hand. She flattened the napkin against the altar and began to write. Riptide’s ink glowed Celestial bronze. “What are you doing?” Percy asked. “Sending a message,” Annabeth said. “I just hope Rachel gets it.” “Rachel?” Percy asked. “You mean our Rachel? Oracle of Delphi Rachel?” “That’s the one.” Annabeth suppressed a smile. Whenever she brought up Rachel’s name, Percy got nervous. At one point, Rachel had been interested in dating Percy. That was ancient history. Rachel and Annabeth were good friends now. But Annabeth didn’t mind making Percy a little uneasy. You had to keep your boyfriend on his toes. Annabeth finished her note and folded the napkin. On the outside, she wrote: Connor, Give this to Rachel. Not a prank. Don’t be a moron. Love, Annabeth She took a deep breath. She was asking Rachel Dare to do something ridiculously dangerous, but it was the only way she could think of to communicate with the Romans—the only way that might avoid bloodshed. “Now I just need to burn it,” she said. “Anybody got a match?” The point of Bob’s spear shot from his broom handle. It sparked against the altar and erupted in silvery fire. “Uh, thanks.” Annabeth lit the napkin and set it on the altar. She watched it crumble to ash and wondered if she was crazy. Could the smoke really make it out of Tartarus? “We should go now,” Bob advised. “Really, really go. Before we are killed.” Annabeth stared at the wall of blackness in front of them. Somewhere in there was a lady who dispensed a Death Mist that might hide them from monsters—a plan recommended by a Titan, one of their bitterest enemies. Another dose of weirdness to explode her brain. “Right,” she said. “I’m ready.” ANNABETH LITERALLY STUMBLED over the second Titan.
