The champagne tower glittered like a monument to excess, each glass perfectly stacked in the grand ballroom of the Harrington estate. Ivy Blake stood at the edge of the celebration, nursing a flute of Dom Pérignon she hadn’t asked for and watching her mother float through the crowd in ivory silk that cost more than Ivy’s first car.
Claire looked happy. Genuinely, luminously happy in a way Ivy hadn’t seen since before everything fell apart.
That should have been enough to silence the knot of unease in Ivy’s chest. It wasn’t.
“You’re scowling at a wedding,” Naomi murmured, appearing at Ivy’s elbow in a sleek burgundy dress that made her look like she’d walked off a runway. “That’s very on-brand for you, but maybe dial it back? Your mom keeps looking over here.”
Ivy smoothed her expression into something more neutral, something that wouldn’t photograph badly when the society pages ran their inevitable spread. “I’m not scowling. I’m observing.”
“You’re judging.”
“Also observing.”
Naomi snorted softly, dark eyes scanning the room with the clinical precision of someone who spent her days in courtrooms dismantling arguments. “Okay, I’ll bite. What’s the verdict on Richard Harrington, other than the obvious fact that he’s obscenely rich and your mom is clearly smitten?”
The obvious fact. As if that covered even a fraction of what churned in Ivy’s gut when she looked at her new stepfather. Richard Harrington stood near the orchestra, silver-haired and commanding in his custom tuxedo, every inch the corporate titan. He had his hand on Claire’s lower back—possessive but not inappropriate, the gesture of a man who’d claimed something precious.
Something that had once belonged to someone else.
“He’s connected to my father’s collapse,” Ivy said quietly, the words bitter on her tongue. “I don’t have proof yet, but I will.”
Naomi’s expression shifted, concern bleeding through her usual composure. “Ivy—”
“I know what you’re going to say. That I’m paranoid. That I see conspiracy everywhere because I can’t accept that Dad made his own mistakes.” Ivy took a longer sip of champagne, letting the bubbles burn. “But the timing was too perfect, Naomi. Dad’s company crashes the same quarter Harrington Industries expands into his market sector? That’s not coincidence.”
“It’s also not evidence.”
“Not yet.”
Before Naomi could argue further, the music swelled and the crowd began to shift, parting like a designer-clad sea. Claire was beaming, gesturing for Ivy to join her at the center of the ballroom. Showtime.
Ivy handed her glass to a passing server and crossed the polished marble floor, hyperaware of the eyes tracking her movement. She’d chosen her dress carefully—midnight blue, elegant but understated, nothing that would upstage the bride or scream desperation. The spark of a forbidden attraction between stepbrother and stepsister wasn’t something she’d anticipated needing to worry about when she’d packed for this weekend.
“Darling!” Claire caught Ivy’s hands, squeezing with genuine warmth that made Ivy’s chest tighten. “I want you to meet someone very important. Theo’s been overseas closing a deal in Singapore, but he made it back just in time.”
Theo. The son. The heir to the Harrington empire that Ivy was now, horrifyingly, connected to by marriage.
She turned, prepared smile already in place, and forgot how to breathe.
Theo Harrington was not what she’d expected.
She’d done her research, obviously—pulled up his LinkedIn profile, scanned the business magazines that fawned over his meteoric rise through Harrington Industries’ executive ranks. The photos had shown someone generically handsome in that way powerful men always were: sharp jaw, expensive haircut, the kind of smile that looked practiced for shareholder meetings.
The photos had lied.
In person, Theo Harrington was devastating. Not handsome—that was too simple a word for the way he commanded space, for the sharp intelligence in storm-gray eyes that assessed her with the same calculating precision she’d just been using on his father. He was tall enough that Ivy had to tilt her chin up despite her heels, broad-shouldered in a way that suggested he actually used the gym membership his wealth afforded rather than just paying for the privilege. Dark hair, artfully disheveled in that way that cost a fortune to achieve. A jaw that could cut glass.
And a mouth that curved into something that wasn’t quite a smile as he extended his hand.
“Ivy,” he said, voice low and smooth as aged whiskey. “I’ve heard a great deal about you.”
The spark of a forbidden attraction between stepbrother and stepsister hit her like a physical thing, electric and unwelcome. His hand was warm when she took it, his grip firm but not aggressive. Professional. Appropriate.
So why did it feel like he was touching far more than her palm?
“All good things, I hope,” Ivy managed, withdrawing her hand perhaps a beat too quickly. His eyes tracked the movement, one dark brow arching infinitesimally.
“Ambiguous things,” Theo corrected, that almost-smile deepening. “My father mentioned you work in marketing. Executive level at twenty-six. Impressive.”
The way he said it made it sound like an accusation.
“I work hard,” Ivy replied coolly, matching his tone. “Some of us don’t have family empires to fall back on.”
The temperature in their small bubble dropped ten degrees. Claire laughed nervously, clearly trying to smooth over the sudden tension, but Richard had noticed now, crossing to join them with the confidence of a man who’d never been denied anything in his life.
“Theo, be nice to your new sister,” Richard chided, but there was amusement in his voice, the tone of someone watching a entertaining performance. “Ivy’s had a difficult few years.”
The reference to her father’s disgrace was deliberate. Casual cruelty wrapped in concern, the kind of power move Ivy had learned to recognize in her clawing climb back to respectability.
“I’m sure Theo didn’t mean anything by it,” Claire interjected quickly, desperate to keep the peace on her wedding day. “You two are going to be family now. I’m sure once you get to know each other—”
“We’re moving Ivy into the penthouse,” Richard announced, cutting through Claire’s rambling with the finality of an executive decision. “No sense maintaining two households when we have more than enough space.”
The penthouse. Theo’s penthouse, technically, the gleaming tower in Manhattan’s most exclusive neighborhood that had been profiled in Architectural Digest last year.
Ivy’s carefully constructed composure cracked. “I have my own apartment.”
“Which you can sublet,” Richard said smoothly. “Claire and I discussed it. It makes financial sense, and it gives you girls a chance to bond while I’m traveling for work.”
You girls. As if she and her mother were accessories to be arranged for his convenience.
Ivy looked at Claire, silently begging her to push back, to remember that Ivy was twenty-six and perfectly capable of managing her own living situation. But Claire just looked hopeful, eyes bright with the naive belief that proximity would somehow manufacture the family dynamic she’d always wanted.
“I think it’s a wonderful idea,” Claire said softly. “We’ve been apart so much since your father… Well. This is a fresh start for all of us.”
The weight of expectation settled on Ivy’s shoulders like a familiar burden. She could argue, could insist on maintaining her independence and watch that hopeful light dim in her mother’s eyes. Could explain that the last thing she wanted was to be trapped under the same roof as the man who’d destroyed her father and his smug, infuriating son.
Or she could smile and nod and use the access to find the proof she needed.
“Of course,” Ivy said, the words tasting like ash. “That sounds… perfect.”
Theo’s expression shifted into something she couldn’t quite read, a flicker of what might have been surprise or respect quickly shuttered behind cool politeness. “I’ll have the guest suite prepared. Third floor, west wing. You’ll have complete privacy.”
“How generous,” Ivy replied, sweetness edged with acid.
The orchestra launched into something bright and celebratory, and Richard pulled Claire onto the dance floor, leaving Ivy and Theo alone in their bubble of crackling tension. Around them, the wedding continued its expensive pageantry, oblivious to the battle lines being drawn.
Theo studied her for a long moment, head tilted slightly as if she were a puzzle he was determined to solve. “You don’t want to be here,” he observed.
“Very astute.”
“And yet you’re going to move into my home anyway.”
“Your father’s home,” Ivy corrected. “Which is apparently my mother’s home now too. I’m just another piece of furniture being rearranged for aesthetic appeal.”
Something flickered in those gray eyes—recognition, maybe, or understanding. It was gone too quickly for Ivy to be sure.
“The penthouse is large enough that we won’t have to interact much,” Theo said, a peace offering of sorts. “I keep irregular hours. You’ll hardly know I’m there.”
“Somehow I doubt that.”
The corner of his mouth twitched. “Are you always this hostile, or am I special?”
“You’re the son of the man who married my mother three years after my father lost everything. You tell me.”
The words hung between them, sharp and ugly and honest. Theo’s expression hardened, the brief moment of détente evaporating like morning mist.
“Your father made his own choices,” he said, voice flat and cold. “No one forced him to overextend his company or make the decisions that tanked his reputation. But if it makes you feel better to blame mine, be my guest.”
Ivy stepped closer, close enough to catch the expensive scent of his cologne, close enough to see the flecks of blue in his gray eyes. Close enough to make it clear she wouldn’t be intimidated.
“I don’t need your permission to blame anyone,” she said softly, dangerously. “And I don’t need your false sympathy about my father. What I need is for you to stay out of my way while I’m living in your precious penthouse.”
“Our penthouse now,” Theo corrected, matching her tone. “And trust me, Ivy—staying out of your way will be my absolute pleasure.”
They stood locked in their silent battle, tension crackling like lightning between them, until Naomi appeared with impeccable timing and a fresh glass of champagne.
“Sorry to interrupt whatever this is,” Naomi said cheerfully, “but your mom is looking for you, Ivy. Something about photos.”
Ivy broke eye contact first, stepping back and accepting the champagne like a lifeline. “Of course. Excuse me.”
She didn’t wait for Theo’s response, just turned and walked away with her spine straight and her head high, even though she could feel his gaze burning into her back like a brand.
“So,” Naomi murmured as they crossed the ballroom, “that’s your new stepbrother?”
“Unfortunately.”
“He’s hot.”
“He’s insufferable.”
“Those things aren’t mutually exclusive.” Naomi shot her a knowing look. “Actually, in your case, they tend to be strongly correlated.”
Ivy elbowed her sharply. “Not helping.”
“Not trying to help. Just observing.”
They found Claire near the cake, radiant and oblivious to the undercurrents threatening to drown her perfect day. Ivy plastered on her most convincing smile and posed for photos, played the dutiful daughter, laughed at jokes that weren’t funny and accepted congratulations from people she’d never met.
And through it all, she felt Theo’s presence like a magnetic pull, always aware of exactly where he was in the room, who he was talking to, when those storm-gray eyes found her across the crowd.
The spark of a forbidden attraction between stepbrother and stepsister wasn’t supposed to feel like this—like warfare and want tangled together until she couldn’t separate them.
It wasn’t supposed to feel like anything at all.
But as the evening wore on and the champagne flowed and the band played songs about love and new beginnings, Ivy couldn’t shake the certainty that moving into Theo Harrington’s penthouse was either going to give her the proof she needed to destroy his father…
Or destroy her instead.
