Recently killed-off  Heroes  cast member Dawn Olivieri  has found new life — as a werewolf on True Blood .
Heroes: Will Lydia's death spell disaster for Samuel? 
Olivieri will play Janice Herveaux, the sister of werewolf Alcide (Joe Manganiello ), the actress' rep confirms to TVGuide.com.
Herveaux is described as a tough-as-nails biker chick who's somewhat protective of her younger brother. She is also into horoscopes and psychics.
Olivieri will first appear in Season 3's fourth episode, "9 Crimes." She also auditioned for the role of Debbie Pelt, Alcide's ex-girlfriend. Casting for that role has yet to be announced.

Olivieri just wrapped up a recurring role on Heroes' fourth season as Lydia, a tattooed empath and member of evil carnival leader Samuel's "family." Her previous credits include My Boys, Entourage, How I Met Your Mother and Cold Case.
