Maggie The Magnificent by Erin Lee

Maggie the Magnificent, the spunky new kid at school, struggles to win over her stand-offish classmates with her not-quite-perfect magic tricks. When this fails, she finds herself promising to magically fulfil one wish for each classmate the very next day. Although she instantly skyrockets to mega-popularity, she soon realizes she'll be magnificently unpopular the next day when her magic tricks do not succeed. Maggie makes one final effort to impress her new classmates, but will it be enough to keep her new friends, or will she destroy the friendships forever?
