Can love be measured? Can destiny be calculated? And if someone you love disappears without leaving a trace, could mathematics help you find the place—or the time—where they have gone?
These questions lie at the heart of my upcoming novel, A Timeless Equation, the fifth book in my Upon a Time series.
The story belongs to Andrew Morris, a brilliant mathematician who has always trusted numbers more than emotions. Numbers are orderly. Predictable. They follow rules and lead to answers.
But there is one mystery Andrew has never been able to solve: the disappearance of his older sister, Nika.
To everyone else, Nika simply vanished under baffling circumstances. Andrew refuses to accept that explanation. He knows his sister would never leave without telling him, and he cannot bring himself to stop searching for her—even when every reasonable possibility has been exhausted.
Then he discovers a mathematical equation that may prove time is not as fixed as it appears.
For Andrew, the equation is more than an intellectual puzzle. It might be the only path leading to Nika. The only chance to discover what happened to her. And perhaps the only way to bring her home.
His search leads him to Scarlett Fitzpatrick, a museum curator whose knowledge of history may be as important as Andrew’s understanding of mathematics. Scarlett is intelligent, independent, and accustomed to protecting her heart. She has no intention of becoming entangled in Andrew’s impossible quest—or in the life of the quietly determined man behind it.
But some mysteries cannot be solved alone.
As Andrew and Scarlett follow the clues, the boundaries between history and the present begin to blur. Paintings hold secrets they should not possess. An old house seems to remember those who passed through it. And a grandfather clock may be more than an elegant relic from another century.
The closer Andrew comes to the truth, the more dangerous his search becomes. Because finding Nika may require him to challenge everything he believes about time, reality, and love.
I have always been fascinated by time-travel stories, but for me, the true heart of such stories is never merely the journey into another era. It is the reason someone is willing to make that journey.
Andrew’s reason begins with devotion to his sister. He refuses to forget her. He refuses to surrender to the impossible. Yet along the way, his search becomes something more. It brings Scarlett into his life and forces him to confront the one force he never expected to encounter in any equation: love.
A Timeless Equation is a story about family, destiny, courage, and the extraordinary things we are willing to risk for the people we cannot bear to lose.
The book will be released on September 22, and today I would love to share a small glimpse of Andrew and Scarlett’s journey with you.

An Excerpt from A Timeless Equation
The redhead caught Andrew’s attention the moment he stepped inside the museum. Her dress—long, fluid, almost shapeless—moved around her tall frame like water, concealing more than it revealed. Deliberate? Or simply comfortable? Probably both.
The interior felt warmer than expected, despite the steady hum of the AC. A space this large must be difficult to cool. Uneasy from the strange episode outside—and his lingering reluctance to enter—Andrew nevertheless sharpened, alert and curious. About her.
Surrounded by a small group of tourists hanging on her every word, she smiled as she spoke—but fatigue showed in the fine lines around her eyes. And what a face. Even in profile, it was arresting. Dusky skin. A generous mouth. An upturned nose. That slightly off-center, pointed chin kept it from perfection. Good. Perfection was overrated. And boring.
Nothing about this woman was boring. Her features were vivid. Alive. Impossible to ignore.
A flame.
Her hair—deep, burnished red—caught the light streaming through the tall windows. Pulled into a high ponytail, it revealed the elegant line of her neck.
A swan’s, he thought absently. Beneath the loose dress, her figure suggested curves. Subtle. But unmistakable. His imagination, unhelpfully, filled in the rest. Andrew flushed.
What the hell is wrong with you?
She looked young. Too young. And here he was—thirty-two—mentally undressing her. Pervert.
He tore his gaze away, forcing himself to focus elsewhere. The furniture. The rugs. The grandfather clock. Anything.
It didn’t work.
Like a magnet, his eyes found her again. This time, she looked straight at him. Their gazes locked. Held. For a heartbeat. Two.
The air between them tightened—charged, electric. He felt it. A pulse. Real.
And then—
The clock.
The steady ticking grew louder. And louder.
Until it filled the room—deep, resonant, almost overwhelming.
They both froze. The sound swelled, then stopped. Abruptly. Silence rushed in. Thick. Heavy.
Broken only by the quiet, familiar tick…tock. Andrew held his breath.
What just happened?
Another episode? Or something else entirely? That connection—brief but undeniable—still hummed through him. Real. Too real to dismiss. And the clock…
That sound hadn’t been normal. It had felt like a warning.
He glanced at her. She was already speaking again, smiling at the departing group as though nothing had happened. Unaffected. Unbothered. As if she hadn’t heard a thing.
He exhaled slowly. Ridiculous. A trick of stress. Had to be it. What else could it be?
Shaken, he turned his attention to the clock. Positioned beneath the sweeping staircase, half-shadowed, it appeared perfectly ordinary. Polished mahogany. A gleaming face. A pendulum swaying in calm, measured rhythm. An object. Nothing more. Relief mingled with something else. Disappointment. For a moment there, he had felt…something extraordinary.
Almost—
No. Don’t go there.
His rational mind snapped back into place.
Get a grip, Morris.
He hadn’t come here for ghosts or fantasies. He needed information. Facts. About the house. About its last owner. That was all.
He scanned the room, looking for another guide. Another staff member. Anyone. No luck.
She was alone. Damn. He braced himself. No way around it. He would have to talk to her.
The last of the tourists filed out, leaving the foyer quiet. Empty. Just the two of them.
He slipped his hands into his pockets, stalling.
Move, Morris.
With a quiet curse, he forced himself forward.
She didn’t move. Didn’t smile. Just watched him approach. The light from the windows wrapped around her, soft and bright, obscuring her features. But not her expression. Startled. Guarded. Like a deer caught in headlights.
He slowed.
Is she afraid of me?
Maybe. Especially after the way he’d been staring. He stopped a few feet away. She stepped back immediately.
Message received. Andrew winced inwardly and summoned what he hoped was a non-threatening smile. Her lips remained pressed together. Her posture tense. Wary.
I wish I could see her eyes.
But the light hid them completely.
“Can I help you, sir?” she asked at last.
