____________________________________

Sarah Fuller has it all—a fragrance empire, a terrace overlooking Central Park, the perfect life. Until a frightening episode shatters everything she thought she knew. Now her husband’s iPhone location is mysteriously off, and the charming widower Harry is impossible to forget.

Haunted by the tarot’s tales of past lives and ancient secrets, Sarah is drawn to Rome—to galleries where Renaissance masterpieces seem to know her name, to shadows of the Inquisition where forbidden love once bloomed, to a truth hidden within the Vatican’s darkest corners.

Who is the woman in those paintings, gazing out across centuries? And why does Sarah recognize herself in her eyes?

From the elite Hamptons to the pyramids of ancient Egypt, from medieval French castles to the dangerous splendor of a newly built Vatican, one woman must unravel the mystery of her soul—before history repeats its most devastating mistake.

This is the story of Arcanum.

In a world where love transcends time, some vows are meant to be broken.

Advance Praise for Book Three in the Arcanum Series:
“Sarah’s journey reminds us that love does not vanish-it endures, waiting patiently for the moment we are ready to receive it again. This story left me with a deep sense of peace, wonder, and the quiet certainty that what is meant for us will always find its way home.”

EXCERPT:

JG Melon, June 13

“God, you look terrible.”

Max held Sarah at arm’s length, nose wrinkled, examining her as if she were Chinese takeout possibly left in the fridge too long.

She wrestled free and gave him a kiss on the cheek. “Well…you look fabulous as always. Are those real glasses or just for effect? They’re…also fabulous.” She slid into a chair.

“They’re genuine tortoise shell. Vintage. Not cheap,” he said. “They’re for reading, but Lord, I’m going to have to take them off for this lunch. I don’t want to be able to see you this well. You need an Instagram filter or something.” He sat down, still eyeing her critically.

“Well, take them off then,” she said. “We certainly know the menu by heart. And I know, I’ve let myself go a little, missed a few waxing appointments and such. If this is what my eyebrows look like, you can only imagine the state of my—”

“Darling, we’re eating,” Max said. “Poor Carl, that’s all I can say. I bet he still looks polished as always.”

“Handsome as ever,” Sarah said, shaking her head. “Shall we order, seeing as I need to put on five pounds immediately?”

“And get to a salon this afternoon!” he said. “Nails, hair, Botox, the whole thing. You are the CEO of a luxury brand, for god’s sake. Thank goodness it’s summer and nearly everyone is out of town.” He waved over Charlie, their favorite waiter.

“The usual?” Charlie said.

“Yes, please, and stat! Sarah looks like she hasn’t eaten in weeks, doesn’t she, Charlie?”

“You two, always bickering like an old married couple,” Charlie said as he walked away, shaking his head.

Max turned to Sarah. “Now. Tell me about my godchild. How is she feeling?”

“Max, it’s incredible. Alex was in the ICU not six weeks ago, and she’s been fully cleared to go to sleepaway camp. The doctor told us that kids recover from her condition quickly, but if you’d asked me in the hospital whether she would make it to camp this year…I didn’t even know if she would make it home by now. It’s as if it never happened.”

“Sarah, that’s such great news,” Max said. “I called Alex the other day and all she could talk about was having gotten excused from the last two weeks of school. She was thrilled! Especially since having a sick twin sister didn’t get her brother the same dispensation.”

Sarah laughed. “Yes, Sam’s hoping for a dire illness, possibly in September.” She covered her face with her hands. “Actually, you know what, it’s too soon to joke about it.”

“Maybe this will help,” Max said as he filled her glass with red wine. They clinked glasses. “To health,” he said.

“To health.” They both took a sip.

“So let me get this straight,” Max said. “Alex has been back to normal for weeks. Carl has not a hair out of place. The camp bags are nearly packed. And you’re still a mess?”

Sarah covered her eyes again. “I knowwww. I just got so close to losing everything. It really rattled me, Max. Stuart and Sofia have basically been running the company for the past several weeks—and honestly everything is going fine. Gallica’s a hit, we had another great harvest of roses in France, my Arcanum core fragrances are doing well. Do you ever feel like your time has come and gone?”

“Sarah, you’re forty-one, even if you do look eighty right now.” Max patted her arm, then topped off her glass. “You’ve got a whole lotta living left to do. What happened to the Sarah who believed in past lives? The Sarah who slayed at that gorgeous launch party for Gallica? Who caught the eye of ‘Manhattan’s Hottest Bachelor’? He was obsessed with you.”

“Was obsessed?” Sarah said, blushing slightly. “I told you what happened in France? Our little tête-à-tête in the ancient forest?”

“And how you insisted that he go through with his engagement to Simone? Yes, you told me.” Max took a copy of the New York Post out of his tote and put his glasses back on. “Sweetie, he took your advice and ran with it. All the way to Harry Winston.”

Author Bio:

When Kelly O’Hearn first stepped off the train in the city of Florence, Italy, as a 20-year-old, she had the overwhelming instinct that she had been there before. In a place famous for its maze of medieval streets, O’Hearn navigated the city as if she had lived there for a lifetime. Born in New York City, O’Hearn first put her intuitive skills to work as a professional wine taster, instructor, and sommelier in the elite institutions of New York, Portugal, and Aspen. After raising her two children and enduring a personal health crisis, in 2012, she was drawn to begin reading the tarot cards, an ancient practice which does not presume to “predict the future” but offers a collection of stories, perspectives, and self-reflections that can guide one to become one’s most authentic self. O’Hearn is in high demand for her readings, with clients on every continent but Antartica. While most people were baking sourdough or riding their Pelotons during the Covid pandemic, O’Hearn used the tarot cards to channel her own past lives. Weeks of readings, all captured on video, yielded six storylines of herself as several powerful women over the millennia and around the globe: the same one soul, over time, persevering against all odds in the quest for happiness and the love of a soul mate. This time-bending saga inspired O’Hearn to conceive of a series of novels titled Arcanum. Book One: In the Temple Shadows is available now. Book Two: Whispers in the Forest will be released Spring of 2025.
