One of the invading souls. Melanie and Wanda's relationship is initially based on their hate for the Seeker, who is described as being irritable for the usually gentle souls. She mocks Wanda for not being able to completely drive out Melanie's spirit. It is later revealed that this is because of her insecurity at not being able to fully drive out the spirit of her body's former tenant, similar to Wanda's predicament. When Wanda goes into hiding with the humans, the Seeker searches relentlessly for her, long after the rest of the search party has given up. When her invading soul is removed, the Seeker's host body remembers her name - Lacey. She is described as short, tiny in fact, with olive-toned skin, long black hair and slightly bulging eyes. Lacey proves to be just as irritating to Wanda and Melanie as the Seeker was. The other humans also quickly accept Lacey, despite her temperament.
