Prologue

The fire took four hours to die.

Aarav was seventeen, standing behind a police barricade in his school uniform with his tie still knotted because nobody had told him yet that there are nights you're allowed to stop being presentable. He remembers a constable's hand landing heavy on his shoulder, smelling of someone else's cigarettes, and the man saying, not unkindly, "Beta, andar nahi ja sakte. Please, stay back."

"That's my house," Aarav had said. As if that settled anything. As if a seventeen-year-old's ownership of a burning building meant something to physics.

"Hum jaante hain," the constable said. We know. "Bas, abhi ruko."

His father had not died in the fire. That was the joke of it, if you could call something like that a joke - Maharaj Pratap Singh Rathore had been found three days earlier in a hotel room two hundred kilometers away, and whatever caught light in the east wing came weeks after, and got blamed eventually on old wiring, because old wiring doesn't need a motive and nobody wanted to go looking for one. Aarav has never once believed that. He has spent eighteen years certain there was a hand behind that match, and he has known, since the morning his mother sat him down at the kitchen table with her eyes red and her voice flat as a closed door, exactly whose hand he was supposed to picture.

"Vikram ne kiya," she'd told him. Vikram did this. "Tumhare papa ke business partner ne. Unhi ne sab kuch barbaad kiya."

Aarav had not asked her how she knew. He was seventeen, and his father was dead, and there is a kind of grief that doesn't want explanations, only somewhere to put its hands.

Eighteen years later, in a study that smells of fresh paint over old stone because the east wing has been rebuilt twice now and still doesn't quite smell like itself, Aarav reads the same résumé for the third time.

Aanya Mehra. B.Arch, heritage conservation specialization. Three award-winning restorations in Rajasthan, including the Devigarh annex, completed two years ahead of —

"You're still awake."

He doesn't look up. He knows the voice, the particular weight of his mother's footsteps on the old marble, the way she always pauses in a doorway like she's asking the house's permission before her own son's.

"Couldn't sleep," he says.

Devika comes in anyway, wraps her shawl tighter, glances at the file in his hands the way she glances at everything - like she already knows what's in it and is only confirming. "Heritage board sent their recommendation?"

"Mehra." He says the name like it's something stuck between his teeth. "Of course it's a Mehra."

His mother is quiet for a second too long. "Aanya Mehra," she says finally, and there's something in the way she says it - not surprise, exactly, but a kind of careful stillness - that he doesn't have the patience to examine tonight.

"You know what that name means in this house."

"I know what you've decided it means," Devika says. "There's a difference, beta."

Aarav sets the file down harder than he means to. "She's Vikram Mehra's daughter."

"She's an architect," Devika says, "with the only certification in the state that lets you open this house to a single guest before the license expires. The board was very clear. There is no one else."

"Find someone else."

"I tried." For the first time her voice softens, almost amused, almost sad. "Beta, ghar wapas banana hai ya purana gussa zinda rakhna hai? Dono ek saath nahi ho sakta." Do you want to rebuild the house, or keep the old anger alive? You can't do both.

He doesn't answer her. He looks at the lake through the window, black glass under a sky with no moon in it, and thinks about a constable's hand on his shoulder and a fire that took four hours to die and a name that has lived in his chest like a splinter for eighteen years, and he thinks: I can hate her and still need her hands on this house. It feels, in that moment, like the only honest thing he's thought all week.

He signs the contract before he can talk himself out of it.

"Bas business hai," he tells his mother, tells himself, tells the empty room after she's gone. It's just business. He will keep this woman at arm's length, hand the daily supervision to his project manager, and in eight months she will collect her fee and her certificate and disappear back into whatever life made a Mehra arrogant enough to think she belongs in this house at all.

He does not know yet that his daughter is going to decide otherwise within the week.

He does not know yet what it will cost him to keep his hatred tidy once he has to watch this woman's hands on his father's stone, every single day, for the better part of a year.

Two hundred kilometers away, in a flat with a water stain shaped like a country on the ceiling and a framed photograph nobody has dusted since the year everything fell apart, Aanya Mehra is folding the same three kurtas into a suitcase for the fourth time, like refolding them will change what's inside.

"Itni jaldi kya hai," her mother says from the kitchen doorway, drying a steel cup with the end of her dupatta. What's the hurry. "Bus toh subah ki hai."

"Bus subah ki hai," Aanya agrees. The bus is in the morning. "But if I don't pack now I'll just sit and overthink it, Maa, and then I won't go at all."

Her brother Kabir looks up from his laptop on the floor, eighteen and built entirely out of nervous energy and engineering pamphlets he's been collecting since February. "Overthink what? It's literally just a job."

"It's literally just a job," Aanya repeats, and even she can hear that she doesn't sound convinced.

Sunita comes and sits on the edge of the bed, the mattress dipping under her like it's tired too. "Project kahan ka hai, bataya nahi tune." You never told me where the project is.

Aanya's hands go still over the suitcase for exactly one second too long. "Udaipur," she says. "A haveli restoration. Big client. The kind that fixes Kabir's tuition problem for the next three years if I do it right."

"Kaunsa haveli?"

She could lie. Her mother has spent eighteen years flinching every time a stranger says their surname out loud at a market stall, and Aanya is not going to be one more person who lets her find things out the hard way.

"Suryagarh," she says. "It's the Rathore family's haveli, Maa."

The steel cup in Sunita's hands doesn't drop. It just goes very, very still, the way her mother goes still - not loud grief, never loud, just a kind of quiet that fills up a room until you can't breathe in it.

"Tu jaa rahi hai," Sunita says slowly. Not a question. You're going.

"I have to. Kabir's fees—"

"Main jaanti hoon," her mother says, and her voice cracks right down the middle of the sentence. I know. "Bas... utna paisa duniya mein nahi hai jitna woh log humse maangenge, beta. Tu unke ghar mein kaam karegi, unhi logon ke beech, jinhone tere papa ko—"

She doesn't finish it. She has never finished that sentence, not once in eighteen years, like the end of it is a door she's too afraid to open even to close it properly.

"I know whose house it is," Aanya says quietly, and zips the suitcase shut before her hands can shake. "I'm not going there to make peace with them, Maa. I'm going there to do my job, take my fee, and come home. That's all this is."

Kabir, sensing the room needs rescuing, holds up his laptop. "Also if they're as rich as everyone says, maybe ask if they need an engineer in five years. Just putting it out there."

"Kabir."

"I'm just saying."

Aanya almost laughs. It's the first easy breath she's taken all evening, and she's grateful for it, because she has a feeling she won't get many more of those once that bus pulls into Udaipur.

She does not know yet that there's a man waiting at the end of a lake road who has spent eighteen years rehearsing exactly how much he's going to hate her on sight.

She does not know yet that his daughter is going to take her hand on the third day and simply never let go of it.

And neither of them knows - not that night, not for a long time after - that the fire which took four hours to die eighteen years ago was never lit by the man either of their families has spent eighteen years burying.
