Honor Among Enemies

Honor Harrington, who was forced into exile due to a scandal, professional jealousies, and political opponents, now gets an opportunity to resume her career as an officer in the Royal Manticoran Navy. There's a catch, however. She has to take charge of a "squadron" of armed merchantmen who have been improvised by the remnants of her army, and manage to prevent the pirates who are robbing the Star Kingdom of its trade by using the Havenite War as an opportunity.
