Chapter 1 - THE SHATTERED GLASS

The sprawling, glass-walled luxury penthouse on the seventy-fifth floor of the Meridian Tower in downtown Chicago was designed to project absolute perfection. Every piece of imported Italian marble, every custom velvet sofa, and every gleaming brass fixture spoke of wealth, status, and untouchable family prestige.
Tonight, however, that immaculate facade was ripped apart by a single, violent scream.
“Get out of my house!” Jessica Vance shrieked, her face contorted with incandescent rage.
Before Sarah could even lift her hands to defend herself, Jessica lunged forward with feline viciousness, her stiletto-clad foot slamming directly into Sarah’s chest. The impact sent Sarah hurtling backward across the polished hardwood floor. She crashed violently into a custom, antique glass-and-mahogany coffee table, shattering the thick tabletop into a thousand glittering shards.
“AHH! Jessica, why?!” Sarah moaned in agonizing pain, her body trapped among the broken glass and splintered wood, blood slowly staining the hem of her designer blouse.
Before the echoes of the crash could fade, the heavy double doors of the penthouse SLAMMED open with deafening force.
Mark Vance strode into the room, his eyes blazing with furious energy. “What is going on in here?!”
The transformation in Jessica was instantaneous. In a fraction of a second, the screaming, violent attacker vanished, replaced by a picture of trembling, tearful innocence. She threw her hands to her face, rushing toward Mark with theatrical hysteria.
“Mark! Oh my god, thank god you're here!” Jessica sobbed, grabbing desperately at his jacket lapels. “She tripped! She fell on her own! I tried to catch her, Mark, I swear I tried, but she lost her balance!”
Mark didn’t look down at her weeping face. His eyes were entirely locked on the broken table and Sarah’s bleeding form crumpled on the floor.
Without uttering a single word of warning, Mark’s hand whipped through the air with lightning speed.
SLAP!
The sharp crack of the open-handed blow echoed off the high glass walls, sending Jessica spinning backward until she hit the marble pillar, her jaw slack with absolute disbelief. Mark didn’t even spare her a second glance. He dropped to his knees beside Sarah, his voice instantly softening into urgent tenderness.
“It's alright. I'm here. You're safe now.”
As Mark gently lifted Sarah into his arms, a sudden, rhythmic electronic pulse chimed from the overhead smart-home control hub mounted near the kitchen archway.
BEEP! FLASH!
A small, high-intensity red LED light blinked erratically on the smart panel’s master diagnostic screen.
Jessica rubbed her stinging cheek, her eyes darting nervously toward the blinking console. “Wait... what is that light?” she muttered, a cold knot tightening in her stomach.

She took three shaky steps toward the monitor, her eyes scanning the live diagnostic stream. The color drained entirely from her face, leaving her looking like a corpse.
“Oh no...” Jessica whispered, her voice dropping into a breathless gasp of pure terror. “It's... it's broadcasting to the whole family network!”
