Delphi in Space Books in Order

With Sakira hidden, the McCormacks build a secret base in the Cook Islands to turn alien tech into something Earth can use. Spies, governments, and corporate pressure threaten the project before Delphi can truly stand.

Keeping Delphi secret is no longer possible once the team's space work starts changing the balance of power. Marc and his allies go public and face the political shock of a new nation holding the high ground of space.

Marc's team is ready to move into orbit by building a space station. Going public with advanced technology may secure humanity's future, but it also puts the McCormacks in direct conflict with world powers.

Marc McCormack finds an alien starship and decides to use it to push Earth toward space. He and a tiny crew must hide the ship, outpace the government, and prepare before its original owners return.

Delphi's city and station are growing, but Earth is still divided over what comes next. When a massive incoming asteroid appears, Marc has to unite rival nations fast enough to survive it.

Earth and Delphi's alien allies each get a chance at a new beginning on distant worlds. Marc works to build a real colony while Catie enters the Academy and both face tests far from home.

With their position secured for the moment, the McCormacks turn outward and find two worlds that might support new colonies. Exploration brings promise, but also hard questions about who should claim the future.

After war and secrecy, everyone on Earth knows Delphi has alien technology. Winning the peace proves harder than winning the fight, as Marc faces politics, leadership, and the cost of reshaping the world.

Artemis comes under threat from the same kind of enemy that once shattered an earlier colony fleet. As Catie nears graduation, Delphi must defend its world and uncover what the attackers really want.

A collapsed wormhole sends Catie into an unexpected system full of wreckage and unanswered questions. Stranded far from plan, she is pulled into local mysteries and another chance to extend Delphi's reach.

Catie is left to manage Onisiwo's transition into the Delphi League while helping repatriate liberated slaves. Real diplomacy proves slow, political, and full of people trying to bend the new order to their advantage.

After defeating the Fazullans, Delphi must deal with freed slaves, bitter enemies, and a third alien people far from home. Catie takes on a mission that could expand the League, if she can hold its ideals together.

Catie continues her campaign to win allies for the Delphi League, this time among the Thoreans. A bad beginning leaves her trying to salvage the mission with nerve, patience, and her own style of diplomacy.

Catie finally visits the starfaring civilizations known to her allies, hoping to bring them into the Delphi League. Instead of a smooth mission, she finds resistance, secrets, and a mystery on Aperanje.

When the League faces a shortage of crucial platinum metals, Catie is asked to build a starbase in a new system. It is a practical mission until greed, sabotage, and risk start closing in.

A wormhole accident throws Jason and Miranda into an unknown system during the war with Thorea. Marooned on a world with stone age humans, they must survive local conflict without revealing who they really are.

Jason's arrest leaves Marc and Catie chasing separate crises at once. While tracing kidnappers and pirates, Catie discovers a larger, rougher league of worlds and a fresh layer of trouble.

This short story returns to the beginning of Delphi through ADI's eyes. It shows how the ship's AI first found Marc and why that meeting changed everything that followed.

Another network of civilizations with jump technology forces the Delphi League to rethink its future. As leaders debate peace, distance, or war, Catie faces a crossroads of her own.

Burned out and restless, Catie disappears into a Volmora colony under a false identity. Even in hiding she stumbles into accusations, theft, and a mystery she must solve without her usual support.
