Private Lucas Walker never thought he'd be a hero. As a grunt in United Federation of Sol's peacekeeper force deployed to Pluto's tiny moon Nyx, the furthest barren hellhole in the solar system, he thought his career was all but over even before it began. He day-dreams of lightsabers, vampires, battlecats, wizards, and all things sci-fi and fantasy while he repairs sand-clogged equipment and mops floors. Then everything changes. A spatial-temporal vortex opens on Pluto, and out pours an army. A deadly force intent on capturing Earth and enslaving humanity in its quest for universal domination. All universes, all galaxies, all planets—all will kneel and submit to The Dominion. The crap has hit the fan. UFS marines are overwhelmed. The odds look grim. Humanity teeters on the edge. The future of civilization now depends on Private Walker and his ragtag band of misfit UFS peacekeepers, armed only with weapons stolen from the enemy. He needs to figure this hero thing out fast, or all is lost. Rebel Sword is a LitRPG Space Opera Fantasy novel, by bestselling science fiction author Nick Webb and Jacob Rennaker, who have teamed up to write the Galactic Knight series.

Private Lucas Walker is on top of the world. He's got a glowing laser sword, a power glove, and a warrior cat he rides into battle—items straight out of his favorite science fiction stories. But this is real life, and he's pretty satisfied with himself for having saved the solar system from invasion. But he can't rest on his laurels. Neptune's moon Triton is the next target of the spatial-temporal vortex, and is invaded by an army of what seem like vampires. And to make matters worse, Walker's newfound powers seem to be fading, and hope seems lost. Earth needs a hero again. Can Private Lucas Walker go two for two? Laser sword? Check. Power glove? Check. Warrior cat? Check. Give the alien vampires an ass-kicking? No problem.

Sergeant Lucas Walker has lost everything – his reputation, his position in the military, and his only friends. Now he’s on his own, tracking down fugitives from his last battle against the Dominion. However, Walker's hunt across the moons of Uranus is interrupted when he rescues an orphaned preteen with an uncanny ability to use the Dominion's weapons. And to make matters worse, another interdimensional portal has opened and an elite Dominion strike force emerges. This time, they're not equipped with claws, lasers swords, or fangs, but with...magic wands? The United Federation of Sol is baffled by these new alien weapons and their only hope is to reinstate Walker—the military's only expert in Old Earth lore. But can Walker convince his former teammates to join him—and his new pint-sized partner—for one more mission before these villains from a suspiciously familiar world of wizards can apparate an entire Dominion army? Or will his preteen protege spell the end of both Walker and our galaxy?
