His son is dead, but his daughter, Valentine, remains. For fifteen years, using several different identities, including that of the She-Wolf, the mysterious leader of the rebellious Wolves of the Forest of Rennes, she organizes a web of intrigue, the sole of aim of which is to restore her daughter and her brother's son to their rightful estate.
