Dr. Thorn. He was hurrying out a door at the opposite end of the gym, steering the di Angelo kids by the scruffs of their necks, like kittens.
I still couldnât see Annabeth, but I knew sheâd be heading the other way, looking for Thalia and Grover.
I almost ran after her, and then I thought, Wait .
I remembered what Thalia had said to me in the entry hall, looking at me all puzzled when I asked about the finger-snap trick: Hasnât Chiron shown you how to do that yet? I thought about the way Grover had turned to her, expecting her to save the day.
Not that I resented Thalia. She was cool. It wasnât her fault her dad was Zeus and she got all the attention. . . . Still, I didnât need to run after her to solve every problem. Besides, there wasnât time. The di Angelos were in danger. They might be long gone by the time I found my friends. I knew monsters. I could handle this myself.
I took Riptide out of my pocket and ran after Dr. Thorn.
* * *
The door led into a dark hallway. I heard sounds of scuffling up ahead, then a painful grunt. I uncapped Riptide.
The pen grew in my hands until I held a bronze Greek sword about three-feet long with a leather-bound grip. The blade glowed faintly, casting a golden light on the rows of lockers.
I jogged down the corridor, but when I got to the other end, no one was there. I opened a door and found myself back in the main entry hall. I was completely turned around. I didnât see Dr. Thorn anywhere, but there on the opposite side of the room were the di Angelo kids. They stood frozen in horror, staring right at me.
I advanced slowly, lowering the tip of my sword. âItâs okay. Iâm not going to hurt you.â
They didnât answer. Their eyes were full of fear. What was wrong with them? Where was Dr. Thorn? Maybe heâd sensed the presence of Riptide and retreated. Monsters hated celestial bronze weapons.
âMy nameâs Percy,â I said, trying to keep my voice level. âIâm going to take you out of here, get you somewhere safe.â
Biancaâs eyes widened. Her fists clenched. Only too late did I realize what her look meant. She wasnât afraid of me. She was trying to warn me.
I whirled around and something went WHIIISH! Pain exploded in my shoulder. A force like a huge hand yanked me backward and slammed me to the wall.
I slashed with my sword but there was nothing to hit.
A cold laugh echoed through the hall.
âYes, Perseus Jackson ,â Dr. Thorn said. His accent mangled the J in my last name. âI know who you are.â
I tried to free my shoulder. My coat and shirt were pinned to the wall by some kind of spikeâa black dagger-like projectile about a foot long. It had grazed the skin of my shoulder as it passed through my clothes, and the cut burned. Iâd felt something like this before. Poison.
I forced myself to concentrate. I would not pass out.
A dark silhouette now moved toward us. Dr. Thorn stepped into the dim light. He still looked human, but his face was ghoulish. He had perfect white teeth and his brown/blue eyes reflected the light of my sword.
âThank you for coming out of the gym,â he said. âI hate middle school dances.â
I tried to swing my sword again, but he was just out of reach.
WHIIIISH! A second projectile shot from somewhere behind Dr. Thorn. He didnât appear to move. It was as if someone invisible were standing behind him, throwing knives.
Next to me, Bianca yelped. The second thorn impaled itself in the stone wall, half an inch from her face.
âAll three of you will come with me,â Dr. Thorn said. âQuietly. Obediently. If you make a single noise, if you call out for help or try to fight, I will show you just how accurately I can throw.â

I didnât know what kind of monster Dr. Thorn was, but he was fast.
Maybe I could defend myself if I could get my shield
