Solar Sail Theory isn’t about finding stronger sources of momentum. It’s about becoming better at capturing thousands of weak sources of momentum that already exist.
One newsletter subscriber won’t change your life. One podcast appearance won’t transform your business. One new reader or conference conversation or bookstore event won’t either.
Individually, they’re almost insignificant.
That’s why the sail is enormous.
After twelve novels and a novella, the journey comes to its conclusion. Camlann, the final novel in Tracy Cooper-Posey’s acclaimed Once and Future Hearts series, is now available from Stories Rule Press and all major retailers.
We all know about compounding, but very few of us truly understand it. The real magic isn’t in one newsletter, one blog post, one book, or one workout. It’s in the quiet accumulation of thousands of small increments that, over time, become something far greater than the sum of their parts. Solar Sail Theory isn’t about finding a shortcut—it’s about patiently building enough sail to catch the wind that’s already there.
Luck isn’t magic, and it isn’t reserved for a chosen few. In publishing, what looks like luck is often the result of years spent building momentum. Every book, every reader, every relationship and every opportunity adds another tiny push. Solar Sail Theory explains why some authors seem luckier than others—and why you can increase your chances of capturing luck without relying on a mythical “big break.”
Book launches aren’t dead. But the idea that every new release must carry your entire publishing business is fading fast. Traditional publishing still depends on launch velocity, but indie authors operate under different physics. Solar Sail Theory shifts the focus from short-term sales bursts to building long-term visibility, discoverability, and audience reach. The bigger your sail, the less any single launch can make—or break—your career.
Every reader matters, no matter where they buy our books. But direct sales give independent publishers something special: the ability to invest more in new stories, create exclusive editions, and build stronger relationships with readers. Here’s why buying direct makes such a difference.
Discovery matters. Visibility matters. But the most valuable reader you’ll ever have isn’t the one who finds your book. It’s the one who chooses to stay connected after they do. Direct sales aren’t just about revenue—they’re about building relationships that can outlast platforms, algorithms, and marketplace changes.
Readers often wonder whether buying books directly from an author’s website really makes a difference. The answer is simple: it does. Direct sales help fund editing, cover design, and future books, while creating a closer connection between readers and the authors whose stories they enjoy.
One of the oldest arguments in publishing is whether writers should write quickly. Solar Sail Theory approaches the question from a different direction. Every book you publish becomes a discoverability asset: another doorway for readers, another wake spreading across the internet, and another opportunity for luck to find you. Fast(er) writers don’t just produce more books—they build bigger sails.
Selling direct isn’t just about keeping a larger share of the sale. From a Solar Sail Theory perspective, direct sales does something even more valuable: it extends your sail and reduces drag at the same time. Every product page, bundle, subscription, and reader resource becomes another opportunity for discovery, while direct relationships with readers create momentum that can continue for years. At the same time, selling direct reduces your dependence on retailer algorithms, visibility changes, and platform policies. Sometimes the best business decisions solve more than one problem at once—and direct sales is one of them.
