The Anxiety of Kalix the Werewolf  (English, Paperback, Millar Martin)

Most of the Scottish Werewolf Clan have a very low opinion of Kalix Macrinnalch, youngest daughter of the Thane. There is little sympathy for her illiteracy, her substance abuse, her self-harming, her eating disorder, her anxiety, depression and propensity for extreme violence. Safe from her clan in London, and living with two friendly students, she's been much calmer. If only she were allowed to live quietly, she might get on top of her problems. Unfortunately, that's difficult for the young werewolf. She's still the number one target for the werewolf hunters, and they're stepping up their efforts to find her. And no matter how Kalix tries to make her life more normal, there will always come a time when, under threat, her insanity and battle-madness will descend on her, and the skinny young girl will again transform into the most feared and ferocious werewolf in the country.
