Blood Royal

"In Blood Royal, the Four Musketeers all venture to England on parallel missions to save King Charles I, pursued by the murderous and vengeful Mordaunt, the son of Milady de Winter, the great villain of The Three Musketeers. Despite all his experience, d'Artagnan is repeatedly foiled by the much-younger Mordaunt, who erupts out of the past to embody the strengths of audacity and cunning that were once d'Artagnan's hallmarks. Mordaunt has corrupted those youthful strengths, and the older d'Artagnan is no match for him until he is able to pull his former team together again. To do this d'Artagnan will have to become a true leader of men, leading not just by example but also by foresight, persuasion, and compromise. Only then can the team of Athos, Porthos, and Aramis be re-formed in all its might to defeat the specter of their past."--Amazon.com
