My beta reader wrote to me just before leaving for class. They’d finished the first twenty chapters of Solar Gate, and on the way out it hit them what was bothering them, which in their words (my translation from Polish) was a plot hole stretching from Earth to the Hyades.
Some context first. Humanity’s biggest colonies are in the Hyades, a star cluster about 150 light-years from Earth, and for a century a wormhole connected them to the Solar System (Sol, in the book), until it collapsed eight years ago. Sol has spent seven of those years in a civil war between Earth, Mars, a loose federation of space stations and a crowd of smaller factions profiting from the mess, so medicine runs short and fuel is rationed by formula.
Then my protagonist, Tom Nowicki, arrives from the Hyades in a ship nobody in Sol can match. He wants the segments of an 800-meter ring from Earth’s shipyard, plus heavy tugs and fuel from Mars. From the stations he asks for forty years of survey records and the crews who used to work around the old wormhole, though he won’t say what any of it is for.
And they all say yes.
Who in their right mind, my reader asked, commits scarce resources in a war economy to something undefined, with no guarantees? Nobody negotiates, and every decision gets made by one person, as if each faction were a dictatorship. My reader didn’t buy it and doubted other readers would, so they suggested a chapter or two from the Solar side, where we’d finally see the factions’ point of view.
Feedback like this is how you avoid the 3-star reviews later.
Why a chapter in the middle is hard
I had a prologue and 24 chapters, about 58,000 words, with the rest of the book still to write. A chapter dropped into the middle has to agree with everything around it: who knows what by which chapter, which ship is where, what each character promised and to whom, even which month it is. Get one fact wrong and you’ve opened a new plot hole while closing the old one.
I’ve written this book in Claude Code from the start: I write the chapters, and Claude keeps them as markdown files next to the worldbuilding codex. The project folder holds the book’s whole paper trail, with a record of what changed in every chapter, a file of canon rulings, a running continuity sheet with every promise and open question, and my style guide. That paper trail is the reason the rest of this worked.
What happened first
Before I touched the manuscript, I pasted the feedback in and had Claude read the chapter records for chapters 9 through 24, along with the scenes where Tom makes his requests. It came back with a diagnosis that partly disagreed with my reader.
My reader wanted pushback, and the pushback is already in the book. In chapter 21 Earth holds back 62 of the 64 segments until Tom says what they’re for, while in chapter 22 Mars won’t release a loaded tug until one of its engineers can inspect the site. By chapter 24 all three factions have pulled out, but my reader stopped at chapter 20, right at the top of what my own notes call a false victory.
On the larger point, Claude was just as plain that my reader was right. In chapters 17 to 19 each leader’s reason for saying yes lived entirely in subtext, because Tom’s point of view never spells it out. Anyone in Sol would read a giant ring built where the old wormhole used to open as a possible way back to the Hyades. Saying yes to the only faster-than-light ship in the system also keeps it away from your enemies, and so far every commitment was small enough to withdraw, yet none of that was on the page. Worse, three leaders in a row declined to ask what it was all for, and three in a row looks like author convenience.
It also suggested that Earth’s leader should guess what the ring is and keep quiet about it, which plants something I can pay off in chapters I haven’t written yet.
Where the chapter came from
The plan I went with was a new chapter between 19 and 20, plus fixes in three earlier chapters, including one scene where a leader finally presses Tom hard on what he’s building.
I told the Earth scenes from the side of Lena Vasquez, Earth’s leader, so the reader would hear her reasoning from her. I gave Mars its own scene, with Adaora Obi, who governs Mars, taking the request to her board and nearly losing, since my reader had asked why nobody inside the factions ever pushes back. Both scenes had to show why each leader says yes. I put Earth’s cabinet meeting on the orbital shipyard, with the segments being cut outside the window, and made the head of Earth’s navy very British, in name and in the way he talks. Outlining each scene, even if only in my head, makes the writing much easier later.
Before I picked a name for him, I had Claude search the earlier books. “Pemberton” already belonged to an admiral from an earlier book, so he became Admiral Sir Giles Hollingworth, a man who says things like “I did think I’d misread that.”
(Every saga eventually has a name-collision problem, and several books in I no longer remember every minor officer I’ve named, so an assistant that checks the back catalog before I name someone saves me the embarrassment I’d otherwise discover in a reader email.)
The chapter
The new chapter (19a, until I renumber everything) has two halves. On Mars, Obi asks the board that shares out Mars’s resources to vote fuel and tugs for Tom with the purpose field left blank, and the board fights her. The member from the fuel office points out that Earth pays for that fuel while Tom pays nothing, and the member for the people on the planet’s surface says those construction crews were promised to a new hospital wing. Obi wins five to four, her narrowest vote ever, and only because the oldest member makes it conditional on an inspection before the fourth tug sails.
On Earth, Vasquez works out alone that the ring is a gate, a doorway back to the Hyades, and keeps it to herself. When she has to defend her yes to her cabinet, her answer to the admiral is the one my beta reader was missing: a price turns it into a contract, which a man with no authority can’t sign; ask him for one and he takes the same question to Mars. Hollingworth gets his price anyway, a frigate escort for anything that goes near Tom’s ship.
The chapters after it read differently now. In chapter 21 the frigate used to arrive as a surprise, and now it’s the admiral’s price, while the inspection Mars demands in chapter 22, which used to look like Obi changing her mind, is the price her board set. Events that already happened later in the book read as consequences.
The question that found the errors
When I finished the chapter, I asked one question: does it fit everything that happened before and after?
Claude went back through chapters 12 to 24, checking every fact the new chapter touched, and found one real contradiction. In my draft, the Mars board’s condition applied before a second tug sailed, but in chapter 21 three tugs arrive with no inspection, and the tug Mars holds back in chapter 22 is the fourth. So the vote became a first batch of three tugs, which also matches the cargo figures announced in chapter 21.
Then came the small slips I probably wouldn’t have caught myself. Hollingworth set down a hat that no line had ever given him, because an earlier edit had cut it. One woman was called the last member of the original Mars board still serving, though Obi had sat on that board too. A clock time was in ship time where it should have been Earth time. The Mars scene, which takes place before the end of chapter 19, had no time cue to tell the reader so, and a line in chapter 18 now contradicted the new vote.
Besides the new chapter, I made small edits to chapters 17, 18 and 19 to fix all of it, and the continuity notes were updated to match.
Read on its own, the new chapter looked clean, yet a separate pass against the surrounding chapters turned up six errors, and that pass happened because I asked for it.
The chapter has gone to my beta reader. Now I wait to hear what they think.
