For decades, space opera has been defined by enormous battles, futuristic weapons, and conflicts fought on a galactic scale. While those elements have helped make the genre popular, science fiction writer Bob Freeman is interested in exploring a different side of the universe. What if humanity’s expansion into space were driven by scientific principles, commercial opportunity, and clever problem-solving rather than an endless cycle of warfare?
That question forms the foundation of Freeman’s five-volume H2LiftShips series. The author has taken familiar space opera conventions and reshaped them into stories that retain the adventure and imagination of the genre while placing greater emphasis on science, humor, and ingenuity.
“I take the tropes of space opera and turn them on their ears,” Freeman says. “Think Star Trek and Star Wars, without the constant fighting and explosions.”
Freeman’s commitment to writing has become a central part of his professional life. After leaving his laboratory software business behind, he turned his attention fully to science fiction. The H2LiftShips saga now comprises five published books, each contributing to a fictional universe built around an unusual but carefully considered approach to space exploration.
At the center of that universe is an alternative vision of how people might travel beyond Earth. Rather than relying on conventional spacecraft and familiar propulsion systems, Freeman imagines hydrogen-filled balloons carrying ships beyond Earth’s gravitational pull. Once the vessels reach the appropriate point, the hydrogen is ignited to provide an additional boost. Their emptied balloon shells are then converted into solar sails, while nuclear-powered boost cannons help propel them across the heliosphere.
The result is a future in which interplanetary transportation and commerce depend on physics, engineering, and economic calculation. As described on the series’ website, the setting resembles our own universe while introducing enough unexpected differences to make it distinctive. Space travel becomes a challenge of resources and risk management, not simply a backdrop for spectacular battles.
The characters navigating this world are just as unconventional as the technology. Captain Graciela leads the LunaCola, a rented solar-sail cargo vessel, after finally stepping out from under the influence of her overbearing mother. Her companions include Jack, a talking dog known for his sharp remarks, fondness for jerky, and talent for Dog Chess; Tang, an orangutan who approaches poker with enthusiasm and a willingness to take extraordinary risks; and Octopus, a composed, water-filled navigation expert responsible for guiding the ship through the darkness of space.
The first installment, Beyond Luna, introduces readers to this unusual crew as they encounter pirates, anarchists, professional gamblers, and a period of imprisonment. Their journey also brings personal conflicts into the wider adventure. When Graciela comes face to face with her manipulative mother on a distant asteroid, the confrontation develops into a high-stakes card game. The outcome could determine not only Graciela’s ability to stand on her own, but also the future of the entire LunaCola crew.
Freeman’s approach occupies an interesting position within the science fiction landscape. The series combines the imaginative spacecraft and expansive settings associated with Star Trek and Star Wars with a greater reliance on strategy and intellect than combat. Its website points to The Hitchhiker’s Guide to the Galaxy as a reference for its humor and layered storytelling, The Expanse for its scientific grounding, and Firefly for its portrayal of communities operating on the fringes of established society.
“It’s an interesting concept on future space travel, wrapped in science and humor,” Freeman explains.
The combination is central to the series’ identity. Science fiction does not necessarily have to sacrifice entertainment to maintain scientific credibility, nor does a technically informed story need to become an exercise in explaining complex theories. Freeman brings together astronomy, chemistry, physics, and engineering with characters and situations that deliberately embrace the absurd. A talking dog capable of playing chess and an orangutan willing to gamble are not distractions from the science; they are part of the imaginative world built around it.
For readers who prefer their fictional conflicts to be resolved through creativity rather than firepower, this approach offers an alternative to more conventional space adventures. The scientific framework gives the setting structure, while the humor makes its characters and situations approachable.
The H2LiftShips experience also reaches beyond the printed editions. Beyond Luna is available as an audiobook lasting more than 12 hours, featuring sound effects and a cast of multiple human voices rather than AI-generated narration. The books are published through IndiesUnited, LLC. The series’ website also features a reader review that playfully challenges anyone claiming to have explored the entire saga to demonstrate that they have read at least one of its installments.
Freeman is also interested in bringing the material to a wider audience through film or television. A cinematic trailer for the books is available on the series’ website, and he is actively pursuing opportunities to adapt the stories for the screen.
“We’re trying to get it into the movies or a TV show,” he says.
Whether the H2LiftShips universe eventually expands into another medium, its central creative idea remains consistent. Freeman is interested in a version of space opera where intelligence, resourcefulness, and scientific understanding carry as much weight as spectacle. By combining recognizable genre conventions with an unconventional crew and a foundation in real-world science, the series presents a different possibility for the future of space fiction: one where exploration can be adventurous, technically imaginative, and genuinely funny.
