Cassandra Winterdawn (more commonly known as Sandra) was the daughter of Jenny and Jeremy Winterdawn. Her eyesight was seriously impaired from a car accident which killed her mother and rendered her father paraplegic.
She was the lover of Justin Cranleigh. After he went mad from using the metahedron, she had an intimate relationship with Harry Truman, not knowing he was an alternate version of Justin created by Gabriel and Tanith.
Later, for their amusement, Gabriel and Tanith altered Sandra's brain, making her insane. She killed Charles Moore Wedderburn and fed his body to his vampiric orchids. They then killed her, wanting to experience what it was like to murder somebody. (PROSE: Falls the Shadow)
