Anita is an immortality quester. In Broken she went missing, and a large amount of blood was found inside her shop, Hecate's Havem. It was believed by the werewolves that she had been killed. However that had never been confirmed.
In Spell Bound Anita appears again, this time under the false identity of a woman named Althea, who helped to kidnap Giles in their quest to reveal the supernaturals to the world, in an attempt to assume control.
