The universe has plans for Kelly and Joe, if only it can put them on the same space station at the same time. Kelly Frank is a junior employee in Earth's diplomatic service who's sick and tired of cleaning up after human tourists behaving badly. Joe McAllister is a reluctant mercenary who's looking for a way out and family-friendly place to start a business and raise an orphaned boy. Will the choices they make in the next few months shape the rest of their lives, or is free will just an illusion in a galaxy managed by ancient artificial intelligence?

Running a galactic empire isn't easy, and one of the best emperors is calling it quits. 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?

Forget about the post-employment future. Everybody works, nobody quits. Kelly returns from sabbatical and finally has the opportunity to expand her embassy with a conference room, providing she can find a contractor willing to take the job. Dorothy finds that her impending motherhood is an advice-magnet to her alien friends, while the SBJ Fashions workplace gets strange as Baa enchants fashion accessories for LARPing to repay her debt to Jeeves. Samuel and Vivian discover that their educational choices don't necessarily match with their aptitudes and abilities.

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 room. Sometimes she has to wonder if the career she has put ahead of her personal life for fifteen years is worth it. When Kelly receives a gift subscription to the dating service that's rumored to be powered by the same benevolent artificial intelligence that runs the huge station, she decides to swallow her pride and give it a shot. But as her dates go from bad to worse, she can only hope that the supposedly omniscient AI is planning a happy ending.

A wealthy alien species is getting rid of all their stuff. There's only one catch. Two years after the events of Alien Night on Union Station, Kelly faces new challenges as the EarthCent Ambassador. The growing acceptance of humans by their alien neighbors plus a measure of her own personal fame (or infamy) is resulting in too much work for an embassy with only two full-time staffers. Friends and family must wonder if the stress is finally getting to Kelly when she starts acting even more peculiar than usual. Just leave it to the Stryx to throw a monkey wrench in the works by offering her a vital new assignment that can't be refused.

What lurks on the hidden decks of a space station that's millions of years old? 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.

You can't hold a book fair without physical books. 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?
