Claire-Kathryn "C.K." Piers is a character in the Charmed novel Between Worlds. She is an untrained witch with the power of Psychokinesis.


Her parents died in a boating accident when she was eight years old, and her paternal grandparents took her in. They knew she was a witch, but hated her magic and taught her to hide it instead of learning to harness it.

At adulthood, she revealed her magic to her fiancé Jace Fraser, and he accepted her for who she was. She was left brokenhearted when Jace died.

She is being used by another witch to destroy the wards between the living and the dead, mainly her hidden grief, which split and became its own manifestation when she cast a spell to restore her riven heart. To save the world, C.K. learned to embrace her grief and was rewarded with the chance to see Jace one last time before he moved on.
