Flag in Exile (book 5) and Honor Among Enemies (book 6).
Still solid entries in the universe. Honor’s role is smaller in each of these books; more scenes are from eleswhere in the universe. The “elsewhere” elements in both books are heaviest up front, making it draggier to finally reach Honor’s part of the book.
Flag in Exile follows Honor’s forced retirement after her duel with Pavel. She’s not retired for long; this book is (partially) about her time running Greyson’s navy. But it’s even more about Greyson politics… it’s well handled, with a big fight, but much of the drama is political and scheming.
Honor Among Enemies returns Honor to Manticore’s navy and a much more intimate command. Several other ships from other forces are developed, including “good men undone by good deeds”–which was great applied to an enemy.
