The Alex Colt Saga

Space Cadet | The Battle of Ganymede | The Secret of the Zark | Dark Matter | The Emperor of Antares | The Great Zark | The Final Battle

After being abducted from Earth by an alien race, Alex Colt must lead a group of misfit galactic cadets in a high-stakes battle against the Zarkians, unraveling conspiracies and fulfilling an ancient prophecy.

Alex Colt is an orphan who has spent his life never quite fitting in—until a push from the top of a playground slide swallows him whole and transports him inside MOTHER, a living mothership that pulses like an organism and serves as the most prestigious cadet academy in the universe.

There, with a Transcerebral Chip implanted in his head and surrounded by a group of companions as unique as they are loyal—the proud Maia, the empathetic Tycho, the chameleon-like strategist Blop, and the small but fearsome Havee—he discovers that humans are considered a “Zero” species, unaware of the existence of extraterrestrial life.

But his arrival is no coincidence: Alex is the key to an ancient prophecy that will pit him against the Zarkians, an ancestral species threatening to destroy Earth. He will also have to confront the fact that his own origin is tied to the enemy in ways he never imagined.

With fast-paced chapters, unexpected twists, and a perfect balance of action, humor, and emotion, the Alex Colt saga hooks readers from the very first page and grows with each installment as its protagonist struggles to discover who he truly is.

In Alex Colt: Space Cadet, Alex is transported by strange mushrooms called chubis aboard MOTHER, where he is implanted with a Transcerebral Chip that allows him to understand alien languages. As he tries to adapt to the academy and faces bullying, he discovers that someone is sabotaging the ship’s engines. Alongside his new friends Maia, Tycho, Blop, and Havee, he ventures into tunnels infested with dangerous space rats and unmasks Professor Banxyn, who is in fact a Zarkian infiltrator. Although he manages to wound her, victory is overshadowed by a greater threat: an enemy ship is heading toward Earth to destroy it in four cycles.

In The Battle of Ganymede, the ship remains stranded in the Solar System, and Alex must prevent MOTHER from fleeing and abandoning humanity. After convincing the captain to stand and fight, he and his four friends discover a secret hangar containing the mythical ship known as Arrow, which can only be piloted by five chosen individuals. With it, they defeat the enemy fleet in a suicidal maneuver over Ganymede—but the celebration is cut short when Alex’s arm transforms into a yellow mass, revealing that the true Zarkian infiltrator is himself.

In The Secret of the Zark, Alex is exiled to Earth, but his ship is shot down and he is captured in Area 51. His friends, convinced of his innocence, rescue him with the help of Ebenezer Colt, a scientist who reveals Alex’s origin: he was born from an alien embryo recovered from the Roswell crash of 1947. They manage to escape, but upon returning to space they discover that MOTHER has disappeared, leaving them adrift with crucial information about the Zark’s plans.

In Dark Matter, with no energy and the Arrow ship damaged, the five friends jump to Hyla, a key planet in the enemy’s plans. There, they are accused of murdering the king and must prove their innocence while Alex uses his Zarkian powers to protect the group. They succeed in exposing the real culprits, but a fleet from the Antares Empire arrives to claim the planet, and Maia reveals that this was her true mission all along.

In The Emperor of Antares, Alex faces rejection from his companions due to his Zarkian transformation, while the occupation of Hyla threatens to trigger a civil war within the Confederation of Planets. Captain Churé assigns them a desperate mission: find Maia, the only one who can stop the conflict. Upon reaching Antares, they discover she is the heir to the throne, but the situation worsens when the Great Zark—a monstrous amalgamation of all Zarkian fragments—detonates the dark matter reserves, leaving the Confederation without energy. Their only hope is to find the legendary solid light.

In The Great Zark, the threat of the Great Zark looms over everything. Guided by a luminous creature, Alex and his friends travel to a secret planet to recover the last solid-light generator. After overcoming dangerous trials, they manage to severely wound the monster—but it escapes. Just as they believe their mission is complete, an enemy mine destroys the Arrow ship, taking away their only weapon.

In The Final Battle, without solid light and with the Confederation on the brink of collapse, a revelation leads them to an ancient temple in Costa Rica, on Earth, where the Eternals—an ancestral race—subject them to individual trials. Alex discovers that the only way to defeat the Great Zark is by using Earth’s nuclear weapons, the “Zero weapons.” In a final confrontation, he infiltrates the monster’s hive mind and forces it to self-destruct, sacrificing himself in the process. After the victory, his friends honor him with statues—but a mysterious epilogue leaves open the possibility that he may one day return.
