“Heads up!” Fang shouted. We had a second to exchange glances, thinking the same thing: We hadn’t seen them on the roof, just minutes before. Where had they come from?

“Up and away!” I yelled to the flock, then saw the problem: Brigid couldn’t fly out with us. We couldn’t leave her to the ninjas’ mercy, or lack thereof. We couldn’t abandon her and the rest of the people who had hosted us.

The officials, Brigid, and the TV crew gazed openmouthed as at least sixty slim, dark figures hit the ground and headed for us. I sized up the situation in an instant: a hundred thousand people who might be injured or killed in crossfire; innocent people right here on the field who would only get in our way; the seven of us up against about sixty of whatever this new threat was.

It was like old times.

“Belay that!” I shouted. “Battle up!”

As a maternal figure, I always try to keep the flock safe, of course. But I admit, it did my heart proud to see the instant blood-lust pop into Gazzy’s blue eyes and to see little Angel automatically tense up and get into fighting stance, ready to rip someone’s head off. They were just so — so dang adorable, sometimes.

We were a tiny bit out of practice. I hadn’t taken anyone apart in several weeks. But once you’ve learned the nasty, street-fighting, no-holds-barred art of Max Kwon Do, you never really forget it.

“Get ’em!” I shouted as the dark figures raced toward us. Liquid-fire adrenaline surged into my veins, making me jittery and lightning fast.

As soon as one was within striking range, I jumped up and out, both feet forward. They connected heavily, slamming the New Threat in its middle. It doubled over but snapped upright quickly, its dark hood slipping back to reveal a weird, humanish face. Humanish except for the glowing green laserlike eyes.

I landed, spun on one heel, and snapkicked backward as hard as I could. I caught it in the shoulder and heard a crunching, breaking sound.

With its good arm, it swung at my head, much faster than a human could and with more force. I leaped backward just in time, feeling the barest brush of its knuckles against my cheek.

A second one rushed up, followed by a third. One grabbed me from behind, tearing my jacket — my new jacket that my mom had given me. Brand-new, not from Goodwill or a Dumpster. He’d torn it.

Now I was mad. A split-second glance revealed that the flock was doing what it did best: deconstructing things. No one needed help, so I balled my fists, put my head down, and went after my attackers.
