She came to sell the house. They came to rebuild it. Now all three of them are under construction.

Elara Cross has a plan: fly in, sell her late grandmother’s lakeside estate, and return to her carefully organized Boston life. One week. Clean break. No complications.

Then she meets the complications.

Cole Ashford is the architect — precise, controlling, and unsettlingly beautiful. He designs rooms. He designs situations. And from the moment Elara walks through the front door, he starts designing something far more dangerous. Jax Morrow is the contractor — enormous, silent, and devastating in ways that words can’t carry. He communicates through construction. Through breakfast. Through the careful, patient labor of a man who builds things because the alternative is remembering what he’s lost.

They’re step-brothers. They share everything. And they want her to stay.

What starts as a week of renovation becomes a summer of demolition — of her plans, her boundaries, and the good-girl mask she’s worn since childhood. Cole draws the blueprints. Jax lays the foundation. And Elara discovers that the woman in the mirror — the hungry, honest, unapologetic one — has been waiting behind the drywall all along.

But houses aren’t the only things with cracks in their foundations. When the outside world intrudes and Elara must choose between the life she planned and the life she’s building, she learns that the strongest structures aren’t the rigid ones — they’re the ones that can hold the weight of three people who’ve decided to stop breaking and start building together.

The Arrival

The GPS died somewhere between the last gas station and the rest of my life.

I should have expected it. The signal had been thinning for the last forty miles, the little blue dot on my phone stuttering and sliding like a drunk on ice, and by the time the rental sedan started climbing the gravel switchbacks above Blackwood Lake, the screen went gray and a polite digital voice informed me that it was “recalculating.” It had been recalculating for eleven minutes.

I wasn’t lost. You can’t be lost when there’s only one road, and the road only goes one direction, and that direction is up. The Blackwood Lake House sat at the top of a mountain that the locals called a hill and the property listing called “elevated lakefront with panoramic views.” What the listing didn’t mention was that the road to the elevated lakefront had the structural integrity of a suggestion and the guardrails of a prayer.

My grandmother had loved this place. Had spent every summer here from 1987 until the year she died, which was this year, which was why I was white-knuckling a rental car up a mountain in rural New Hampshire instead of sitting at my desk in Boston doing the thing I was actually good at: organizing other people’s chaos into color-coded spreadsheets.

I had a spreadsheet for this trip. Of course I did. It was titled “Blackwood Lake Estate — Liquidation Timeline” and it lived in a folder called “Grandmother’s House” which lived inside a folder called “Family Obligations” which lived on my desktop between “Tax Documents” and “Therapy Homework.” The spreadsheet had fourteen columns, forty-seven rows, and a Gantt chart that mapped every hour of my planned one-week stay. Arrive Monday. Meet with the property assessor Tuesday. Photograph the interior Wednesday. Consult with a realtor Thursday. List the property Friday. Drive home Saturday. Cry about it Sunday.

The spreadsheet did not have a column for “GPS failure.” It did not have a column for “road conditions: apocalyptic.” And it definitely did not have a column for what I found when I finally crested the last switchback, pulled into the gravel clearing that served as a driveway, and saw the house.

Or rather — saw what was happening to the house.

The Blackwood Lake House was a three-story cedar-and-stone structure that my grandmother had built in 1985 with money she’d earned selling watercolors to tourists and spite she’d earned from a divorce that had made local legend. It sat on four acres of lakefront property, backed by forest, faced by water, and it had been — in my memory, which admittedly stopped at age thirteen — a place of tremendous, rambling beauty. Wraparound porch. Stone chimney. Windows that caught the afternoon light and held it like cupped hands.

What I saw now was a construction zone.

The porch railing was gone — not broken, removed, the posts standing like teeth in a gap-toothed smile. A section of the south-facing wall had been stripped to the studs, the exposed framing raw and pale against the weathered cedar. Tarps covered portions of the roof. Sawhorses flanked the front door. And from somewhere inside the house, deep in its wooden guts, came the rhythmic, concussive sound of a sledgehammer hitting something that had been standing for forty years and was now, emphatically, not.

I sat in the car and stared.

The spreadsheet had not accounted for this.

Frequently Asked Questions

Is The Shared Foundation spicy?

Extremely. Heat level: 🌶️🌶️🌶️🌶️🌶️ (Scorching). This is dark erotica with explicit MFM ménage scenes, BDSM elements, power exchange, breeding kink, exhibitionism, and emotional intensity. The steam escalates throughout and includes DP, mirror play, sensory deprivation, and more.

Is this a why choose / ménage romance?

Yes! Elara ends up with both Cole and Jax — no choosing required. The novel is MFM (the men are step-brothers but not romantically involved with each other) with a guaranteed happily-ever-after for all three. The relationship is built on communication, consent, and a literal contract.

What’s the dynamic between the two men?

Cole is the architect — cerebral, controlling, dominant, and emotionally guarded. Jax is the contractor — massive, silent, tender, and carrying trauma from military service. They’re step-brothers with a deep bond, and their dynamic with Elara is complementary: Cole designs, Jax builds, and Elara holds the vision together.

Is there bonus content available?

Yes! There’s an exclusive bonus chapter set one year after the epilogue — the contract’s anniversary, a weekend without the baby, and a renewal clause that involves the boathouse, the bathroom mirrors, and a blindfold. Read it here.
