A Manga

Amazing Agent Luna is not your average book. It is what is called a manga. An action packed, spy/romance book, it tells the tale of an utterly inexperienced young girl trying to find her way in highschool, while trying to gather information for her spy agency. This sweet and lovable manga series is addictive and funny, sweet and sad and best of all, unpredictable. Luna the main character is a sweet, efficient girl-spy, and the Bookworm definitely recommends her to you.
