Building Book Three While Book Two Is Still Moving

Calculus of Trust is with beta readers. The draft is solid, the feedback is coming, and there’s nothing I can do to the manuscript until it arrives.

So I’ve been working on Book Three.

Not in a vague, “thinking about ideas” way. The high-level plot is done. Every chapter has a purpose. The major beats are mapped from opening to close. The plot holes I found when I got to that level of detail have been identified and fixed.

Now I’m building out the chapter-level outlines—and once those are in place, I’ll start the first draft.

Why Now

Waiting on feedback doesn’t mean stopping.

The obvious risk of starting Book Three before Book Two is locked is that things change. Beta feedback might require structural adjustments. Scenes might move. Something I thought was settled might turn out not to be.

That’s real. But it’s manageable.

The alternative—doing nothing while feedback trickles in—isn’t actually safer. It just means arriving at the other side of the beta cycle with nothing to show for the gap.

The high-level work on Book Three is stable enough to build on. The parts that might shift are in the detail, and the detail comes later.

A Trilogy Is a System

This is where working on a trilogy gets genuinely complicated.

Three books aren’t three separate stories that happen to share characters. They’re one system. And like any system, the pieces have dependencies.

There are things established in Book Two that Book Three needs to exist. Capabilities, decisions, consequences—structural facts about the world that Book Three builds on. If any of those shift in revision, I need to know before I’ve committed too deeply to the downstream work.

And there are things in Book Three that reach back. Moments that only pay off because of something that happened earlier. Threads that were planted in Books One and Two that Book Three is responsible for resolving.

Which means I can’t finalise Book Three in isolation. It has to be consistent with what Book Two actually is—not just what I think it is right now.

The Thread

There’s a running thread between two characters that starts as a throwaway moment in Book One—the kind of thing that’s easy to miss.

It gets a single callback in Book Two. Just enough to keep it alive without drawing attention to it.

In Book Three, it becomes a trap-door.

The references had to be there from the beginning, and they had to feel like nothing—because the moment they feel like setup, the payoff stops working. That’s a different kind of constraint than plot logistics. It’s about earning a moment across three books without telegraphing it.

Getting that right meant going back through Books One and Two to make sure the groundwork was actually there, in the right places, with the right weight—or lack of it.

That’s the kind of work that only becomes visible when you’re looking at the whole system at once.

How the Outlining Works

The high-level outline is coarse. This chapter, the characters discover something. They react in this way. They move here. It’s enough to see the shape of the story and catch the places where the logic doesn’t hold.

That’s where the plot holes live—not in the big picture, but in the transition from “this needs to happen” to “here’s specifically how it happens.” Things that seem connected at the high level turn out to have gaps when you get to the detail.

The chapter-level outline fills those gaps.

For each chapter, I work through: who’s in it and what emotional state they’re arriving with; what continuity points need to be honoured from the previous chapter; what the concrete outcome is—plot and emotional; the tone and how it moves; and the key beats, scene by scene, with the emotional shift and character arc movement for each one.

It’s more structured than it might sound (blame the software dev background), but the structure is useful. It forces precision. You can’t hide a weak scene behind vague intent when you have to specify exactly what changes for each character by the end of it.

What I’m Waiting On

The chapter-level work is underway. The first draft will start once enough of that outline is in place to build from.

But there’s a ceiling on how far I can take Book Three before Book Two is locked.

Some of what I’ve outlined depends on specifics that are still technically in flux—things that are 95% settled but not 100%. Drafting into that uncertainty is fine up to a point. Past that point, I’m building on ground that might shift.

So the process runs in parallel until it can’t, and then it waits.

Beta feedback on Book Two will close the loop. Once I know the manuscript is stable, I can finalise the pieces of Book Three that depend on it—and the first draft can move without a ceiling.

Where Things Stand

• Calculus of Trust: Draft 3.3, with beta readers. August/September release still the target.
• Book Three: High-level outline complete, plot holes addressed, chapter-level outlining underway, first draft starting.
• The system: holding together, dependencies mapped, threads accounted for.

Still a lot of work ahead. But the direction is clear and the pieces are moving.
