Earth Cent Ambassador Books in Order

Five years later, Kelly is married and still trying to make humans matter on Union Station. A mysterious new game begins shifting power between species, Joe starts a microbrewery, and Kelly's mother arrives at exactly the wrong time.

Kelly Frank is Earth's top diplomat on Union Station, underpaid, overworked, and not thrilled about the AI-run dating service her friends give her as a gift. As one awful date follows another, diplomacy and romance start colliding.

Humanity's standing on Union Station is improving, but that only means more work lands on Kelly's desk. As her fame grows and the embassy strains under it, the Stryx hand her a new assignment that cannot be refused.

Union Station is about to hold its first carnival since humanity joined the galactic community, and every ambassador is dragged into the royal election. Kelly wants no part of the spotlight, which only makes the whole spectacle harder to survive.

The Cayl Empire is winding down, and the Stryx want Union Station to help sell the rest of the galaxy on what comes next. Kelly is asked to host an open house, but not everyone wants the merger to happen.

Kelly decides humanity needs its own intelligence service, but EarthCent has no real experience with spies. Building a secret agency from scratch on Union Station turns into exactly the kind of clever, messy diplomacy problem she cannot ignore.

After the Wanderers move on, Kelly is ready for her first real vacation in fifteen years. Bad luck and EarthCent policy have other ideas, and a quiet break on Union Station soon turns into another round of embassy mischief.

Years have passed, the children are growing up, and Aisha is moving into a new career. Then a swarm of alien wanderers settles near Union Station and arrives with news of another wave of helpful AI, which may be more trouble than help.

Kelly heads to Earth for the first Conference of EarthCent Ambassadors and leaves Union Station in other hands. Naturally, that is exactly when everyone else starts making trouble, and the embassy has to muddle through without its usual anchor.

Kelly sees a huge chance to reconnect far-flung human communities when EarthCent gets access to Flower, a vast colony ship. At the same time, publishing takes off on Union Station, turning books, status, and competition into serious business.

Back from sabbatical, Kelly wants to expand the embassy with a badly needed conference room, if she can find anyone willing to build it. Meanwhile, Dorothy faces a flood of advice and Samuel and Vivian rethink where their talents really fit.

A brand-new species appears in the Sol system, and the humans get the greeting assignment. While Dorothy and Kevin head out on a trading trip and Samuel and Vivian start university, the station's family ties and responsibilities keep growing.

Kelly needs a research project for sabbatical just as live-action role-playing sweeps across Union Station. Between a for-credit LARP, Dorothy's wedding dress, and Jeeves's schemes, everyday station life gets delightfully stranger than usual.

After more than twenty years on Union Station, Kelly still has one huge problem: humanity is only on probation. When the Stryx announce a review of EarthCent's status, she faces the test of her entire diplomatic career.

Harry and Irene think they have bought a peaceful retirement in space, while Julie Gold is hiding from the criminals she testified against. Both end up aboard Flower, a sharp-tongued sentient colony ship with plans of her own.

Rumors about the Stryx put Kelly in the awkward position of defending the AIs who keep the tunnel network running. At the same time, Dorothy's return to work and Samuel and Vivian's co-op plans turn station life into fresh chaos.

Two years before Kelly Frank becomes Earth's ambassador, she is a junior diplomat cleaning up after human tourists. Joe McAllister is looking for a safer life with an orphaned boy, and their choices quietly set the whole Union Station story in motion.
