In the aftermath of a foiled invasion, the troubled hub of a thousand worlds has become isolated.

Someone broke the interplanetary elevator, and no one knows how to fix it, not even Jeff Abel, the Galactic Commons newest citizen.

But mankind's first ambassador to another world has other problems.

Two thousand extraterrestrials are stranded back on Earth.

Jordan, the only other human in the alien city, isn't returning his calls. And Irving the Grey, the mastermind behind the city's woes, has escaped.

It has begun to dawn on Jeff that getting a job with Galactic Commons security wasn't his brightest idea.

House of the Galactic Elevator is the sequel to 2015's A Beginner's Guide to Invading Earth.
