Harry's POV

"Hey Harry? Do you know where's Percy? He's been gone for over half an hour and I'm getting really worried. He was suppose to meet me fifteen minutes ago," Annabeth's upset tone filled my ears as she appeared next to me.

"I have no idea. Do you think he's with Nico?" I asked her, craning my neck, trying to find Percy in the crowd.

"Nope, because I'm right here," Nico replied, standing on my other side. The bookshop was filled to bursting with people and Molly really wanted to just pay for the books and leave. Unfortunately, Percy chose that time to disappear.

I pushed my way through the crowd, looking for familiar faces with Annabeth and Nico right behind me. The shop was really crowded and even I was feeling a little stifled but we needed to find Percy first. We reached the front of the shop, where everybody was gathered, patiently waiting.

"Any sign of him?" Molly asked anxiously, clearly eager to leave.

I shook my head and she sighed, bracing herself to fight her way through the crowd again. Clarisse gave a snort and shook her head in disgust while Tyson looked ready to cry. He was really super protective of his half-brother.

"There he is!" Grover exclaimed, a relieved smile spreading over his face. Thalia grinned over at Annabeth whose eyes were twinkling as Percy walked over to us, his face expressionless. Tyson immediately beamed happily.

"Where're your books? Didn't you get them?" Ron groaned, hating the thought of having to go back in there. Annabeth threw her arms around Percy but her expression turned confused when he didn't bother lifting his arms to hug her back.

"What's wrong Percy?" She asked, holding him at arm's length, her hands on his shoulders. He ignored her and turned towards me, his eyes blank.

A cold shiver went up my back. Something was seriously wrong here. Percy's a cheerful person although he can be moody sometimes and he would never dare to ignore Annabeth. Especially seeing how much he loves her. "Annabeth, get away from Percy," I warned her, my eyes fixed on Percy, whose face was still void of emotions.

"What're you talking about, Harry?" She asked, her expression confused as her hands fell away from Percy's shoulders.

"Annabeth, get - " I started to yell when Percy unsheathed his sword and shoved Annabeth away. She landed on the ground with a bump, staring at him with a hurt and shocked expression.

Thalia quickly ran over to her and helped her up, putting an arm around her comfortingly while glaring at Percy. "What is your problem, Seaweed Brain?" She demanded furiously.

"Harry Potter," He said, his face still expressionless and his voice monotonous.

"Blimey, I think he's under a spell. Probably the Imperius Curse," Ron muttered to me as we pulled out our wands. "Remember how Mad-Eye Moody placed it on us? That's exactly how he looks like."

"Capture Harry Potter," Percy murmured as if under a trance. His head suddenly snapped up and his green eyes glared at me. Gripping his sword tight, he charged.

Taken by surprise, I would've been dead had not Ron push me out of the way. Percy's sword slashed down at the spot where my whole body had been a few second ago. He whirled around just as Arthur raised his wand, with a resigned but determined look on his face.

"Stupefy!" He yelled. A jet of red light flew out from his wand, aiming straight at Percy's face but he was quicker. He threw himself to the side, landing behind an alleyway between two shops. By this time, the commotion had attracted the attention of everyone in the crowd. Panicked shouts and mutters filled the air as people rushed away in fear, not realising that they one attacking didn't have magic.
