Query: The best book I have read in two years

"Face on the milk carton", is the best book that I have read in two years. Jannie (the main character in the book), is having the worst year of her life. It all began in the lunch room when she decided that she wanted to drink one of the cartons of milk that her friend didn't want; when she was done with the milk she was throwing it away and as she was putting it in the trash can she noticed that there was a picture on the back. The picture was of a girl wearing a polka-dot black dress that she had seen about four nights ago when she was up in the attic. She got a suspicion about it; so about for three weeks she was researching on the face on the milk carton. If you read more of the book you will get into it more and more every chapter. This is the best book I have ever read, why? The book always went into detail and you would never get tired of reading it. I recommend this book for ages 13-16 it is a great book and you will be glad that you read it.
