John E. Siers Books in Order

Fleet Academy recruits Lorna Greenwood and Nova Sakura expect years of training before command. Pirate encounters and combat make their education immediately dangerous, while assignments after graduation bring them face to face with a possible interstellar war.

Ten years after establishing independence on the Moon, the Lunar Free State encounters an alien probe near Saturn. Its disappearance reveals the possibility of interstellar travel, forcing humanity to master the technology before unknown visitors arrive themselves.

Billionaire Ian Stevens secretly assembles scientists and engineers to develop gravity-powered spacecraft and establish a lunar settlement. With government agencies closing in on his research institute, he must launch his project before officials discover and shut it down.

The Lunar Free State launches a campaign to liberate Tatanna from alien occupation. Lorna Greenwood faces her first command and Nova Sakura returns to unfinished business, while another enemy prepares to strike much closer to their home.

The Lunar Free State learns that alien predators are using a human-inhabited planet as a hunting preserve. Its Marines prepare to intervene, but uncertain enemy technology makes protecting the population a mission that could turn rescuers into prey.

Lorna Greenwood takes command of an elderly Lunar warship and a crew with much to learn. With the recent war over, their assignment seems unlikely to involve combat, but the ship’s limitations soon matter more than anyone expected.

Teenage inventor Aphrodite Kim opens a repair business in the Lunar capital, offering practical solutions to expensive imports. A customer’s apparently simple electronic modification conceals a software secret that draws her into dangerous interplanetary espionage and intrigue.

Luna and Earth race to colonise an apparently uninhabited planet, only to discover intelligent, telepathic feline inhabitants. As rival forces gather in orbit and on the surface, competing claims threaten to ignite a much wider war.

A Lunar contact team visits Ragnarok, where survivors of nuclear devastation insist they have renounced war. Rival factions and covert interference from Earth undermine that promise, pulling the Lunar Free State into a conflict that spreads beyond the planet.

A coalition of seven Earth nations enters the long rivalry between Luna and the Confederated Nations, deploying its own interstellar forces. Both established powers hesitate, but covert operatives threaten to turn the newcomers’ arrival into another dangerous confrontation.

Former admiral Robert O’Hara finds governing Luna harder than commanding its fleet as expensive colonial competition strains the economy. Constitutional opposition grows, concealing a deeper conspiracy that threatens to alter the foundations of the Lunar Free State.

Recovering from recession, the Lunar Free State risks losing its independence through debts owed to Earth. Some conspirators favour conquest over gradual influence, preparing a devastating surprise attack that a handful of Lunar military patriots must resist.

After open war ends, Earth’s defeated Confederated Nations turn to covert attacks against Lunar allies on Tatanna and Xanadu. Deep-cover agents and assassination teams face unexpected resistance from religious allies and the planet’s intelligent, telepathic feline predators.
