Two years after the discovery that Earth Prime 4-6-4-0-8-9 dash Omega is in imminent danger of collapse, the Transdimensional Authority has helped hundreds of millions... well, millions... okay, a lot of aliens immigrate to Earth Prime. How's that working out?
Rodney Pendleton, the first alien to make the move, is now a tech millionaire (hover technology is wildly popular - who knew?). Wainwright Walsh, lead singer for The Occidental Tourists (ask your parents... or, maybe your grandparents), puts together an all-star band to raise funds for a foundation to help the aliens adjust to their new home.
But all is not beat yas and scream on Earth Prime. An investigation into the first murder of an alien being leads to an anti-alien protest group, revealing a dark, speciesist strain of human emotion. And a different investigation into the disappearance of aliens in Latin America reveals a dark, greedy strain of human emotion.
It turns out, some problems cannot be solved by the swift, unexpected application of pie!
