A few days before one of my books is released, I always find myself thinking about the journey that brought it into being—and about the readers who are preparing to enter its world for the first time.
By the time a book reaches publication day, I have lived with its characters for so long that they no longer feel imaginary to me. I know their fears, their secrets, their stubborn habits, and the truths they are not yet ready to admit to themselves. Letting readers meet them is exciting, but it also feels a little like introducing close friends and hoping they will be loved.
A Timeless Equation, Book Five in my Upon a Time series, will be released on September 22. Before it arrives, I would like to share five things about the story—without revealing the secrets waiting inside.
1. The Story Begins With a Brother’s Love
At the center of A Timeless Equation is Andrew Morris, Nika’s younger brother.
Andrew is a mathematician—a man who believes that every problem has an answer if one is patient, disciplined, and clever enough to find it. Numbers follow rules. Equations can be tested. Patterns may be hidden, but they exist. His sister’s disappearance follows no rules at all. Nika seemingly vanished under baffling circumstances, leaving behind questions no one could answer. As time passes, others begin to accept that the mystery may never be solved. Andrew cannot.
His determination to understand what happened to Nika becomes the driving force behind his work. He is not interested in theories for the sake of intellectual curiosity. He is searching for something deeply personal: a path to the sister he refuses to believe is beyond his reach.
Long before this becomes a story about time, it is a story about family—and about the promises we make to the people we love, even when they are not there to hear them.
2. The Mathematics Matters—but the Heart Matters More
The title A Timeless Equation reflects Andrew’s world. He trusts mathematics because it offers him order in a life disrupted by the impossible. But what happens when the numbers begin to suggest something that logic says cannot exist? Andrew’s calculations lead him toward a possibility too extraordinary to accept and too compelling to ignore. The equation may offer a path, but mathematics alone cannot prepare him for what waits at the end of it.
Numbers can reveal coordinates. They can expose patterns. They can point toward a door. But they cannot tell Andrew whether he should open it. That decision requires something far less predictable than logic. It requires courage, faith, and the willingness to risk everything for an answer he may not be ready to receive.
This is one of the ideas I loved exploring while writing the novel: even the most rational person may eventually encounter something that cannot be understood by reason alone.
Sometimes, the mind takes us as far as it can. The heart must carry us the rest of the way.
3. Scarlett Has Questions of Her Own
Scarlett Fitzpatrick is a curator, a woman trained to examine the past through the objects and stories it leaves behind. She understands that history is never truly silent. It speaks through paintings, documents, photographs, forgotten belongings, and details that seem insignificant until someone looks closely enough.
Scarlett is intelligent, observant, and grounded. Yet she, too, becomes drawn into a mystery that challenges everything she believes she knows about the past. Her connection with Andrew begins amid questions neither of them can answer easily. He is searching for his sister. Scarlett is trying to understand discoveries that should not be possible. Together, they begin following clues that connect mathematics, art, history, and Coleman House in ways neither of them expected.
But Scarlett is not simply waiting beside Andrew while he follows his quest. She has her own voice, her own strength, and her own reasons for needing the truth. Andrew may be determined to solve the equation, but Scarlett helps him understand that not every answer can be calculated—and that finding what we have lost is not the same as knowing what to do once it is found.
4. Coleman House Still Has Secrets to Reveal

Readers of the Upon a Time series already know that Coleman House is more than a setting. It has witnessed love, separation, sacrifice, and reunion. Its rooms carry memories from more than one lifetime, while the grandfather clock at its heart continues to guard secrets that few people would ever believe.
In A Timeless Equation, the house once again becomes part of the mystery.
Andrew approaches it differently from those who came before him. He does not begin with faith in the impossible. He begins with calculations, coordinates, and the conviction that there must be a rational explanation. Coleman House is not particularly interested in rational explanations. There are places that seem to remember everyone who has passed through them. Places where the past never feels entirely gone and where time appears thinner somehow—as though one moment might still be able to reach another.
For Andrew and Scarlett, the house offers both possibility and danger. It may hold the answer they have been seeking, but it will not surrender that answer easily.
And the grandfather clock is waiting.
5. Every Answer Comes With a Price
We often imagine that discovering the truth will bring relief. Sometimes it does. But answers can also create new questions. They can demand choices we never expected to make. They can change our understanding of the past and leave us standing before a future that suddenly looks very different.
Andrew believes that finding the solution will be the most difficult part of his journey. It is not.
The true challenge begins when the impossible becomes real and he must decide how far he is willing to go—and what he is prepared to leave behind. That is the emotional heart of A Timeless Equation. It is not simply a story about whether time can be crossed. It is about what makes someone attempt the crossing in the first place.
How much would you risk for someone you love? Could you walk away after discovering that the impossible was within reach? And if you finally found the answer you had sacrificed so much to obtain, would it give you peace—or ask even more of you?
The Door Is Almost Open
A Timeless Equation is a story about mathematics and mystery, but it is also about siblings, family, grief, devotion, and a love that appears where it is least expected. It is about the courage to keep searching when everyone else has stopped. It is about the traces people leave behind and the invisible threads that continue to connect us across years, distances, and lives. Most of all, it is about the moment when a man who trusts only what he can prove must decide whether he is willing to believe in something impossible.
The equation has been solved. Coleman House is waiting. And on September 22, the door will open.
