My Magic Wand focuses on a girl, Lily, who is spending her day being treated for cancer at a hospital. Lily carries around a wand with her that allows her to transform the halls of the hospitals to whatever magical location she desires. She shares this wand with various other characters that appear throughout the story, who are pediatric cancer patients, like her, or children facing various kinds of critical illnesses, to help them get rid of their fears until she has to go in for a procedure. After her procedure, she meets a very scared girl who is sharing the hospital room with her. From this interaction, she decides to teach others how to make her wand so everyone can find the sunny side of their situation at all times.
