The Bastard Legion, Book 2
FRIENDLY FIRE, the Bastard Legion are hired to pull off a daring power-armoured heist of propriety tech.
A crime-ridden colony world holds the secret to a potential alien contact, and various groups of mercenaries have been hired to discover it. None of the rest of them have little bombs implanted in their heads, though, so the Bastards have an advantage when it comes to motivation. And Miska, their commander and kidnapper both, is still on the hunt for the people who killed her father.
People who might still be among her convicts.
Getting the tech will be hard. Getting off the planet, deadly.
