Like Starship Troopers on crack! -Goodreads reviewer
Ambushed behind enemy lines and left for dead along with a handful of privates so green they actually respect his authority, Lance Cpl. Lucky Lee Savage has to master his inner demons, manage the ambitions of his foul-mouthed AI, and figure out what is tearing a hole in the fabric of space-time before everything goes tits up.
Lucky wouldn’t bet on the universe.
One thing he will bet on: Somewhere, somehow, somebody is going to pay for all this. And he is going to be right there to pull the trigger.
If you like Aliens and Firefly, you'll LOVE this funny, gritty, and endlessly entertaining series!
