Poul Anderson's "Operation Chaos" and its sequel "Operation Luna" have as their protagonist a completely positive and heroic werewolf, who is in complete control of transformation from human to wolf and back, and completely retains his normal mind while in wolf form - being thus able to use the wolf form to fight evil, in the manner of superheroes endowed with a superpower. An earlier Anderson novel, "Three Hearts and Three Lions", with its semi-medieval settling, featured a more traditional werewolf - a young girl transformed against her will and in wolf form perpetrating acts which she does not remember when returning to human form. Even so, she is depicted sympathetically as a victim, and a solution is found by taking her far away from the influence of evil magic, to a location where she would not change again and where she could get happily married.
