This series is fabulous. I highly recommend it, even to people that don't like Sci-fi. The interaction between the characters is wonderful.
Another fine book in David Weber's Honor Harrington series.
The Proles are revolting. The families who rule the People's Republic of Haven are in trouble. The treasury's empty, the Proles are restless, and civil war is imminent.
But the ruling class knows what they need to stay in power: another short, victorious war to unite the people and fill the treasury once more. It's a card they've played often in the last half-century, always successfully, since they've been careful to attack only single-system polities. All that stands in their way is the Star Kingdom of Manticore and its threadbare allies. Enemies in the past have always backed down to Haven's overwhelming might.
Only this time the Peeps face something different. This time they're up against Captain Honor Harrington and a Royal Manticoran Navy that's prepared to give them a war that's far from short, and anything but victorious!
