His eyes narrowed. Even at the library, he had never seen her compose an explosive device of that size. She was smiling now, a crazed, gleeful smile.

 

Adrian squeezed the trigger.

 

The dart disappeared into the grasses behind her. He cursed.

 

The Detonator laughed. “Now, you just wait your turn over there, sweetheart. I’ll get to you next.” The explosive was bigger than a basketball, glowing in bright, swirling blue.

 

“Ingrid?” said Nightmare, and the slight quiver to her voice brought Adrian’s attention back to her, even as he hurried to load another dart. “What are you doing?”

 

Adrian hesitated. There was something familiar about her in that moment. Something that gnawed at him. Had she ever, for a moment, appeared vulnerable when he had fought her before? He didn’t think so.

 

“If I’m going to die,” said the Detonator, “it’s not going to be alone.”

 

Nightmare shifted—an almost imperceptible change. Her stance widened. Her head tilted down. Her shoulders tensed as she turned, ready to launch herself off the stairs and away from the fun house.

 

The Detonator hurled the bomb at her.

 

Nightmare was a moment too late.

 

The explosion knocked Adrian onto his back. A flash blinded him, washing out the sky overhead, leaving him trying to blink the shadowy stars from his eyes. His head rang. His whole body vibrated from the impact. The world smelled of smoke and dust.

 

Coughing, he rolled onto his side and took off his glasses, rubbing the lenses on his uniform to wipe away the dirt. He was still plagued with sparklers in his gaze when he put them back on and pushed himself up to his elbows. The canoe had been turned over onto its side, and he wondered how much it had protected him from the surge of shrapnel and flying rubble.

 

Half of the fun house was gone.

 

Broken floorboards and a few of the interior rooms were left exposed, including the metal slide and the hall of mirrors, which was now littered with broken glass. Wooden beams and siding and roof shingles were scattered across the ground in all directions. The pitched roof was toppling inward, ready to cave onto the mound of smoking wood and plaster beneath.

 

The Detonator had fallen forward onto her stomach. Her hair and clothing had turned chalky gray from all the dust, and the blood from her wounds was clumping in the dirt around her. She was not moving.

 

Adrian searched for any sign of Nightmare, who had been standing in the very spot where the great mountain of debris was smoldering. She could have been buried beneath, or, more likely, she could have been blown apart by the explosion.

 

Shaking, Adrian got back to his feet and tucked the gun into the back of his pants. He stared at the exposed insides of the fun house. A few small fires were scattered throughout the wreckage, sending plumes of black smoke toward the darkening sky. Somewhere inside he could hear the jack-in-the-box laughing.

 

His heart started to pound erratically. “Nova…”

 

His disbelief was quickly overcome with denial, and he lifted his wrist. “Nova—Insomnia, where are you? Report.” Stumbling around the canoe, he picked his way through the remains of the building, searching the corners of its crumbling skeleton. “Nova!”

 

He was trying to navigate the destroyed outer wall when his eye caught on something shining beneath a fallen window shutter. He kicked the shutter out of the way, stooped, and picked up the slim, molded piece of steel.

 

Nightmare’s face mask.

 

Turning it over, he saw that one side of it was streaked with blood.

 

A tittering laugh made his skin prickle. Adrian tossed the mask aside and turned to see the Detonator on her hands and knees, still chortling. She spat, then sat back on her heels and wiped the dirt from her mouth.

 

She was drenched in blood.

 

He stared at her, stunned. He wasn’t surprised that she would survive the explosion. From what he’d seen at the library, she appeared to be immune to the blasts of her own bombs. But she had been shot so many times, she had lost so much blood …

 

How was she still alive? And … laughing?

 

With a delirious grin, the Detonator climbed to her feet. She seemed to wobble for a moment, but then she shook out her matted hair and her stance solidified. “I don’t know who’s more gullible,” she said, rolling her shoulders. “Nightmare … or you.”

 

Adrian was too distracted for her taunting. He found his attention constantly shifting around the park, hoping to see some sign of Nova.

 

The Detonator clapped her hands together, knocking off some of the dust. “That was fun, wasn’t it? That little spat of ours. It was all staged for your benefit, you know, so I hope you were entertained.”

 

He frowned. His pulse was beginning to race again, his instincts humming with warnings—but also curiosity.

 

“You see?” said the Detonator, swiping her fingers through the caked blood on her abdomen. “Fake blood. She was firing blanks. You know, Queen Bee thinks she’s the only savvy actress around, but I think I’ve proved otherwise.”

 

Adrian shook his head. “What are you talking about?”

 

“Don’t you see? We planned this all, to make you think that we were both dead. So you would stop looking for us. Get it now?”

 

He stared at her.

 

“I know, I know. You’re thinking … so why is Nightmare actually dead, then? And why am I giving up our villainous plan now, when we almost got away with it?” She staggered forward, and though she didn’t seem to be in pain, she wasn’t moving as gracefully as normal, either. Adrian wondered if creating a bomb that size had drained her. “It’s too bad, really. I liked Nightmare. Always have. She was a lot like me in a lot of ways—always willing to do what had to be done. But I could see the writing on the wall. It was only a matter of time before she betrayed us, betrayed all of us. And I couldn’t have that. So … she had to go. Problem solved.”

 

Adrian was still frowning, still confused. “Is this…,” he started, dismayed, “a villain speech?”

 

Ingrid laughed. “Maybe so. It’s horrible to go through all this plotting and have no one around to appreciate it. Besides, you’ll be dead soon, too, so it’s not really going to matter.”

 

Adrian reached for the gun, but he had barely gotten his fingers around the handle when a glowing blue marble smashed into the ground at his feet, blowing a small crater into the earth and knocking him onto a pile of splintered siding and wooden studs. A sharp pain tore through his tricep and he cried out, tearing his arm away from the nail that was sticking up through one of old trim boards.

 

Hissing, he scrambled to sit up.

 

The Detonator sauntered closer, gathering more power around her hands. “It’s time to finish what we started at the library.”

 

Adrian snarled and clenched his fist, drawing on the power of the cylindrical tattoo on his forearm. Within seconds, his arm from fingers to elbow had begun to glow molten white.

 

The Detonator paused.

 

Before Adrian was entirely sure this would work without being in the Sentinel’s armor, a long metal cylinder emerged from his skin. He fired, striking the villain in the chest with a single bolt of blinding energy. She was blown back, smacking hard into the puppet theater. The mannequins trembled and clacked together.

 

The cylinder retreated into his flesh and Adrian clambered to his feet, trying to find purchase on the shifting piles of wreckage beneath him. He staggered forward, retrieving his gun.

 

The Detonator coughed and placed a hand over her chest, where the beam had hit her. Her breathing was raspy and labored as she met his eyes.

 

“Fine. Let’s finish what we started at the library,” said Adrian. “No—actually, let’s finish what started ten years ago.” He came to stand half a dozen feet away from her and raised the gun, confident that even he could hit her from this distance. “Nightmare knew who killed my mother, and you just took that one lead away from me. But you’re an Anarchist, so maybe you have some answers too.”

 

In response, she began to laugh again. Dazed and maniacal. “The Sentinel,” she gasped. “You’re the Sentinel. Oh, that’s rich.”

 

His eyebrow began to twitch. “Who killed Lady Indomitable?”

 

Her cackle turned to a wheeze as she studied him. “You’re going to threaten me into submission with … what? A tranquilizer? Life imprisonment?” She smirked. “I seem to recall you were eager to negotiate with the Librarian. Don’t I get the same treatment?”

 

He held her gaze, considering, trying to discern if she really had the information he wanted, or if this was just her trying to play him again.

 

And even if she did know, could he really bargain with her, after everything?

 

“No,” he said. “The Renegades are done negotiating with Anarchists.”

 

Stepping forward, he dug the handcuffs from his pocket and yanked the Detonator’s wrists forward, binding them together. He could just see the amused twinge enter her eye when he pulled out his marker and began to draw lines crisscrossing her hands.
