A misfit military force on a delivery assignment ends up fighting a war in this comical science fiction adventure from a New York Times–bestselling author.

Afterword by John Ringo

The auxiliary scout platoon known as the Cockroaches contains all the outsiders and oddballs the Galactic Defense Force doesn't want to have to deal with, but can't find a way to discharge from the Space Service. They're savvy, street-smart, wise (if not book-learned), intelligent, survival-oriented, and completely unconventional. Lt. David Wolfe is their new CO: young, idealistic, and gung-ho, but even he has a secret that forced Central Command to shift him out of the line of fire.

The Cockroaches get sent on what ought to be a simple courier mission to the greatest amusement park in the Galaxy, and end up defending the population from a ruthless enemy in the only way the Cockroaches know how: unconventionally!
