The phrase “aliens on vacation book” primarily functions as a compound noun. It identifies a specific type of literary work centered on extraterrestrial beings taking leisure time. For example, one could say: “I purchased the ‘aliens on vacation book’ at the bookstore,” where the phrase acts as the object of the verb “purchased.”
