The Book
You pick up your phone and text your best friend a picture of some pages of the book. You ask her if she has ever seen anything like the language and she responds that she hasn't, but that another of her friends might know. When she mentions the name, you recognize it as belonging to probably the most untrustworthy boy in the school. He is very smart, and you understand why your friend mentioned him, but he collects strange books, and you just know he will want to steal yours.
