Cassandra Cillian

As far back as Cassandra can remember, she's always been smart, gifted with a photographic memory and incredible calculating skills supported by the gift of synesthesia - the ability to link all five senses to her memory. For Cassandra, numbers appear as colors, science as musical notes, and when she does math she smells things... mostly breakfast. . But ever since a life-threatening tumor (affectionately referred to as her "brain grape") began metastasizing inside her head, her gift has become a curse, overwhelming her with hallucinations. Cassandra now strives to use her gifts to combine the mysteries of science and magic before her time finally runs out...
