I’m going to be honest with you in a way that I suspect will make a lot of writers feel significantly better about their own process.
I have 58 books in a fictional hockey universe. I have a 385 page series bible. I know the roster of every team in two leagues, the front office of every franchise, the names and numbers of cheer squads, the career arcs of players across three league levels, and the precise emotional geography of a family of twins and singletons whose love stories span multiple continents and decades.
And the timeline is the thing that keeps me up at night.
Not the characters. Not the plots. Not the emotional arcs or the romantic beats or the question of whether a particular scene is doing enough work. The timeline. The question of whether the events of Bergen’s book are sitting correctly in relation to the events of Deacon’s book, whether Grayson’s shoulder injury happened in the right season relative to Isla’s labral tear, whether Niklas’s rookie year overlaps precisely with Sorrenson’s story in the way it needs to for the secret to be the secret it has to be.
I have all 58 stories written. My current editing run — the one I am living inside right now, the one that is simultaneously thrilling and mildly terrifying — is dedicated almost entirely to making sure the timeline works. That every season is the right season. That every trade lands in the correct moment. That nobody is in two places at once and no career arc contradicts itself and the through-lines that connect all 58 books into a single coherent universe are actually doing what I need them to do.
It is the hardest part of building a universe at this scale.
It is also, I have come to believe, the most important.
Why Timeline Breaks Everything
A timeline error in a standalone novel is unfortunate. A timeline error in a 58 book universe is a fault line that runs through everything built on top of it.
This is the particular vulnerability of interconnected series — the same quality that makes them so rich and rewarding for readers, the fact that everything connects to everything else, is exactly what makes a single continuity error so consequential. If Bergen’s book establishes that Per died in the off-season between two specific years, then every subsequent book that references Per’s absence has to be consistent with that timing. If Grayson’s Seattle chapter covers a specific number of seasons before he returns to Portland, then his age at every point in the timeline has to reflect that accurately. If Isla McKenzie’s rehab overlaps with Grayson’s rehab in the way the story requires, the timing of both their injuries has to be architecturally possible within the hockey season calendar.
None of this is insurmountable. All of it requires rigorous, unglamorous, painstaking attention to detail that is about as far from the romantic inspiration of first-draft writing as it’s possible to get.
This is the part of universe-building that nobody tells you about when you fall in love with the idea of writing a series.
The Hockey Calendar Is Your Spine
The single most useful thing I can tell you about managing timeline in hockey romance specifically is this: the hockey calendar is not a constraint. It is your architecture.
An NHL season runs from October through April for the regular season, with playoffs extending into June for the teams that go deep. The draft happens in late June. Free agency opens in July. Training camp begins in September. This annual cycle — absolutely fixed, publicly documented, consistent year over year — is the spine on which every career arc in your universe hangs.
This means that certain things can only happen at certain times. A trade deadline move happens in late February or early March — not November, not May. A rookie arriving from the draft is arriving in September for training camp, not January. A player rehabbing from an injury sustained in the playoffs has a very specific window of recovery time before the next season begins, and whether they make it back or don’t make it back is determined by the nature of the injury and the length of that window.
These fixed points are gifts. They mean that if you know what season a story is set in and what time of year key events occur, a significant portion of your timeline is determined for you by the sport itself rather than by your creative choices. You’re not inventing when things happen. You’re discovering when they have to happen given the constraints of the world you’ve chosen.
Build a master calendar that maps your entire universe onto the actual hockey calendar. Every book, every key event, every career milestone — anchored to a specific month and year. This document is not exciting to create. It is absolutely essential to maintain.
Career Arcs Across Multiple Books
The particular complexity of a hockey romance universe isn’t just that multiple books are happening simultaneously — it’s that your characters appear across each other’s stories at different stages of their careers, and those appearances have to be consistent with where each character actually is at that moment in time.
Bergen Worth appears in Deacon’s book as a 28 year old captain who has already lost his parents. He appears in Grayson’s book as an older brother watching his youngest sibling fall for an Australian figure skater. Every time Bergen appears in someone else’s story, his age, his circumstances, his relationship status, and his emotional state have to reflect where his own timeline has placed him at that point.
Multiply this across 58 books and an ensemble cast of hundreds of characters and you understand why the editing run I’m currently doing exists.
The tool I’ve found most useful for managing this is a character timeline document that sits alongside the series bible — a linear record for each significant character that maps their age, career stage, relationship status, and key life events against the master calendar. When Bergen appears in chapter four of someone else’s book, I can check his timeline document and confirm exactly who he is at that moment.
It sounds like an enormous amount of administrative work.
It is an enormous amount of administrative work.
It is also what stands between a universe that feels coherent and alive and one that quietly undermines itself through accumulated inconsistency.
The Particular Problem of Trades
Trades are the element of hockey timeline architecture that cause me the most specific difficulty, and I suspect I’m not alone in this.
A trade is by definition a disruption — a player moving from one team to another, which changes their relationships, their living situation, their professional context, and their proximity to everyone they know. In a universe where multiple teams are interconnected — where the Pioneers play the Trade Winds, where the California teams share family members with the Portland world, where the women’s league exists alongside the men’s — a single trade has ripple effects across multiple storylines.
If a trade moves a character at the wrong moment in their timeline, it doesn’t just affect their own story. It affects every other story that character touches at that point. The timing of trades therefore needs to be determined not just by what makes sense for individual storylines but by what the entire universe can accommodate at that moment.
I plot trades on the master calendar before I finalise them in any individual book. I need to see the impact across the whole before I commit to any part of it.
When You Find the Error
You will find errors. I want to say this clearly and without softening it because I think writers who are building complex universes sometimes feel that finding a continuity error is evidence of failure rather than a normal and inevitable part of the process.
I have found errors in my editing run. I will probably find more before it’s complete. Some of them are small — a character’s age stated incorrectly in a throwaway line, a reference to an event that the timeline places in the wrong season. Some of them are larger — a career arc that doesn’t quite work when you lay it against the master calendar, a relationship development that is moving faster or slower than the established timeline permits.
The process of finding and fixing these errors is not failure. It is the editing run doing exactly what it’s supposed to do. The errors existed whether you found them or not. Finding them means your readers won’t find them first.
When you find an error in a complex interconnected universe, the fix has to account for every place that error has consequences. Change the date of one event and you may need to adjust three other books. This is painstaking and occasionally maddening and absolutely worth every minute it takes.
Making Peace With Imperfection At Scale
Here is the truth that I have had to make peace with across 58 books: at this scale, absolute perfection of timeline is probably not achievable. Not because the work isn’t worth doing — it absolutely is — but because the sheer volume of interconnection means that the number of potential conflict points is staggering, and the human brain, even one that has been living inside this universe for years, has limits.
What you are aiming for is not perfection. You are aiming for coherence — a timeline that feels consistent and trustworthy to your reader, that doesn’t break their immersion in the world you’ve built, that honours the investment they’ve made in following these characters across multiple books.
Most readers are not reading your 58 book universe with a spreadsheet open beside them tracking dates and ages and career statistics. They are reading because they love these people and they trust you to take care of the world those people live in. That trust is what you’re protecting with every hour you spend on the editing run that nobody will ever see.
The timeline work is invisible when it’s done right.
That’s exactly how it should be.
Do it anyway. Do it thoroughly. Do it with the same love you brought to creating January Jones Jarvis and Kon and Isla McKenzie and every other person you’ve built a life for inside these pages.
They deserve a world that holds together.
So do your readers.
