Sylvia is a spectrophobic. A girl who believes she's fine. But, her fears eventually starts getting stricter to her and she does not feel that way any longer. Her best friend, Celeste, and her Psychologist, Stag, help her figure what's wrong. But, the TRUTH lies somewhere in the grey. Though the novel is entirely based on that grey, it will enter your dreams in screaming colours.
