No Retreat

When things are going to plan, check to see what you’re missing.
Admiral Jack Romanoff and his crew are trapped inside the Confederation proper and facing an unknown number of alien attack ships. They’d thought the Tardan military was defeated, but they’d been wrong. Now they were trapped in a fight they couldn’t lose.
When everything seems exactly as you’d hoped, figure out what you’ve missed.
Not only do they need to stop the Locusts, but they still have to defeat the Poseidon Group and overturn the coup they’d staged. They only have two battleships and a spy ship to make that happen. Their only advantage is that no one knows they’re there. They’ll have one chance to get things right, or humanity is screwed.
When everything goes to hell and your back is against the wall, fight.
