CATCH-UP GUIDE

Expeditionary Force

By Craig Alanson

Earth has been secretly conquered and liberated — sort of. Now a small crew aboard a stolen alien ship, led by a barely-qualified soldier and an insufferably sarcastic AI named Skippy, has to figure out how to actually save humanity. These catch-up guides are written for readers returning to the series — or for newcomers who want to know what they're in for before committing to book one.
