France, 1648: Richelieu and Louis XIII are dead, the new king is a minor, and the Duc de Lavalle is in virtually open rebellion, scheming to seize power. As a last resort, Queen Anne summons the heirs of the original Musketeers to her aid...including Claire, daughter of Athos, who when she chooses can miraculously pass as a boy, and wields as fine a sword as any. All their skills will be needed for a battle against increasing odds. One for all and all for one!
