The Last Plank

For ninety years, the wreck of an ore hauler has drifted through the Flora debris stream, and Wren has come to cut it apart for titanium. She is a salvager with a paid-off ship, a grumbling partner, and no patience for anything that doesn't pay for reaction mass. Then her thermal sweep catches something it shouldn't: a dark stone nodule half-buried in the rubble, three degrees warmer than the rock around it, pulsing on a schedule that no battery and no isotope could keep. When the pulse arrives thirty-six minutes early, as if it knew she was reaching for it, Wren leaves the scrap behind and takes the stone instead.

Inside the glass is a human brain, vitrified and braided through with a strange carbon-silicon lattice, frozen mid-transfer at forty-one percent. The timing points to one man: Dr. Idris Kell, the brilliant, abrasive physicist who vanished when the research ship Kestrel Margin broke apart in 2207, taking his unfinished theory of mind transfer with him. High on a mountain in Chile's Atacama Desert, Wren and three artificial minds of very different temperaments coax the substrate back to life. It grows in the sunlight. It lights up nine point four seconds before every dawn. And slowly, piece by piece, something inside it begins to speak.

The voice that emerges is not quite Kell, and not quite anyone else. Every memory he recovers costs him another, and every answer raises a harder question. Is he the man who died in the belt, owing debts to a wife, a daughter, a crew, and three patients lost to his methods? Or is he someone new, free to set that past down? What really happened in the final minutes aboard the Kestrel Margin, and whose life paid for his survival?

The Last Plank is a hard science fiction novel about salvage in every sense: of metal, of memory, and of a self that has been rebuilt one plank at a time. Morgan Burns brings the grit of deep-space labor and the precision of real physics to the oldest question we have about identity. If every part of you is replaced, are you still the same ship, and do you still owe what the old one left unpaid?
