Alien artificial intelligence has brought humanity onto a galactic tunnel network
Finding a match for the top human diplomat on Union Station is another story...

Kelly Frank is EarthCent's top diplomat on Union Station, but her job description has always been a bit vague. The pay is horrible and she's in hock up to her ears for her furniture, which is likely to end up in a corridor because she's behind on rent for her

...

The Wanderers have just moved on from Union Station, and the ambassador is ready to take her first vacation in fifteen years. Unfortunately, the rules on paid vacation for EarthCent employees have changed for the worse, retroactively. Libby suggests spending some time exploring the station as an alternative, and Kelly cautiously goes along with it. Back at the embassy, while the cat's away, the mice will play.

A new species has jumped into the Sol system for a quick look, leading the Stryx to assign humans to the greeting mission. Dorothy and Kevin leave on a trading mission in his new ship, bringing the dog, and Samuel and Vivian start at the Open University.

The Stryx offer EarthCent help in reaching out to the wide-spread human communities, but as usual, it comes with a catch or two. Kelly see an opportunity to increase her book hoard, just as publishing on Union Station begins to take off and Donna's daughters enter a friendly competition. But who will publish the most expensive book of all?

The story picks up less than a year after the events of High Priest on Union Station, with Kelly coming to the conclusion that EarthCent needs an intelligence service. Of course, EarthCent has no institutional knowledge of what spies do, or how they work, so the new agency gets off to a slow start. Then Kelly and the Union Station crew come up with a brilliant idea.

Five years after the events of Date Night on Union Station, Kelly has settled into married life and her job as the EarthCent ambassador. The only fly in the ointment is that most of the aliens on Union Station refuse to talk to her. But a mysterious new game is sweeping the galaxy, changing the balance of power between species and bringing game-savvy humans front-and-center. As the invitations to diplomatic functions pour in, Kelly finds herself struggling...

On the other side of the galaxy, the Cayl Empire has decided to wind down operations and the Stryx are planning to pick up the pieces. Kelly is tapped to host an open house event on Union Station to tempt the aliens into joining up, but does anybody other than the Stryx actually want the merger to take place?

Kelly has served as the ambassador on Union Station for over two decades, but humanity remains on probationary status. When the Stryx inform EarthCent that their membership status is under review, Kelly goes all out to prepare for the test of her lifetime.
