Columbus Day: Expeditionary Force, Book 1 / Craig Alanson

Nominee, 2018 Audie Awards - Audiobook of the Year

We were fighting on the wrong side of a war we couldn't win. And that was the good news. 

The Ruhar hit us on Columbus Day. There we were, innocently drifting along the cosmos on our little blue marble, like the Native Americans in 1492. Over the horizon came ships of a technologically advanced, aggressive culture, and BAM! There went the good old days, when humans got killed only by each other. So, Columbus Day. It fits. 

When the morning sky twinkled again, this time with Kristang starships jumping in to hammer the Ruhar, we thought we were saved. The UN Expeditionary Force hitched a ride on Kristang ships to fight the Ruhar wherever our new allies thought we could be useful. So, I went from fighting with the US Army in Nigeria to fighting in space. It was lies, all of it. We shouldn't even be fighting the Ruhar; they aren't our enemy. Our allies are. 

I'd better start at the beginning.
