BORN IN 1998…
Before he was a universe, a book series, or a brand... Marsus was a doodle.
It was 1998. Before SpaceX, before Wi-Fi, back when the internet screamed like a dying robot every time you tried to connect. A mom, a creative rebel, and a woman with very strong opinions about aliens, was running a small printing company when inspiration struck.
Mainly, she thought aliens were ugly.
So she did what creative rebels do best: she made her own...
The drawing became an illustration, a book, a live show and a very famous green alien. But then life happened. Cancer arrived like a storm no one saw coming. She fought it with everything she had... and won. But the financial weight of two years of illness grounded her Marsus dream. The show stopped. The laughter faded.
Marsus returned to his planet.
And for decades, he waited. A small green spark of unfinished magic, tucked quietly into the background of her life.
“My mom's dream never faded...it was just waiting for its right time to shine.”
-Julie St-Louis, Author & Founder
MEET THE CREATOR
Hi, I’m Julie.
Storyteller, former professional stuntwoman, entrepreneur, and unapologetic space nerd. I basically grew up orbiting Marsus. As a kid, I ran around backstage helping build sets, practicing lines, and bringing a curious little green Martian to life. Marsus was never just a character to me. He was part of the family. He taught me that imagination is not simply make-believe. It is the engine behind every impossible idea that eventually becomes real.
Then, one night in 2024, I stood outside my home and watched a SpaceX Falcon 9 tear across the sky. And I knew it was time for Marsus to rise again. Not inside the same story, but at the center of an entirely new Universe. For the past two years, I have poured my heart into writing Rise of the Explorers, the first book in the Marsus Universe series. I created a world beneath the surface of Mars and filled it with the strangest, funniest, most wonderfully chaotic crew on the planet: Marsus, Oppy, Blorp, Jake, and Lily.
Somewhere along the way, they stopped feeling like characters I had created. They became part of me. Or maybe each of them carries a piece of who I am. If a book could hold a human heart, mine would be inside these pages.
I brought Marsus back for a few important reasons.
First, to carry forward the dream that began with my mom. She created Marsus in the 1990s, long before the world was ready for him. I now have the honor of continuing that legacy and taking our favorite little Martian somewhere he has always belonged. In the hearts of children around the globe!
Second, I wanted to play my part in something much bigger than myself. Humanity is preparing to become a multi-planetary species. Space companies (what’s up Space X 👀) are building the rockets and technology that will carry us to the red planet. I am building the stories that will inspire the next generation of space generation explorers who will be among the first to live on Mars.
And since I am no engineer and putting me in charge of a rocket launch would be highly irresponsible, instead, I contribute to this mission by doing what I do best: I tell stories. Stories that spark curiosity. Stories that make science feel like an adventure. Stories that help kids dream beyond what currently seems possible and believe they have a place in the future humanity is building.
This is my way of laying one small brick in the foundation of a multi-planetary world.
And finally, I wrote this book for the kids like me. The ones who never quite fit in. The thinkers, dreamers, inventors, over-analyzers, and beautifully unconventional minds running on a completely different operating system. The kids who feel out of sync with the world around them, but perfectly in tune with the future they can already see.
Rise of the Explorers is a story about space, friendship, courage, real science, and one strange green kid who has spent his entire life being told that his ideas are too much. Until those ideas become exactly what everyone needs. Because being different is not something to fix. It may be the very superpower that helps move humanity forward.
