When the Tide Rises (The Republic of Cinnabar Navy series #6)

When the Republic of Cinnabar doesn't have enough battleships to deal with all the crises in its war with the Alliance, it sends the next best thing: Commander Daniel Leary and his friend, the spy Adele Mundy. This time they're off to help the Bagarian cluster in its rebellion against the Alliance, but they'll quickly find that the worst threats to the rebels are the treacherous politicians.

Leary and Mundy use electronic espionage, sub-machine guns, and shipkilling missiles to outwit political rivals, put down mutiny, and capture an Alliance fortress. When all else fails, they'll strike for the heart of the Alliance--and then throw their tiny corvette into a major fleet action.
