This is a fantastic book about a girl named Janie. She is 15 and is an only child. Janie is a normal high school girl until one day she is at lunch with her friend and on the back of her milk carton she sees a picture of a little girl in a polka dotted dress that went missing about a decade ago. Janie instantly recognizes this girl and knows that it is her. She is the missing person. Janie starts noticing around her house how her parents have no baby pictures of her. Janie is confused and scared not knowing if her parents are actually related to her and maybe that they kidnapped her. This book is very engaging and will keep you on your toes.
If you like this book read the rest of the series: Whatever Happened to Janie? The Voice On The Radio What Janie Found, Janie Face to Face. I read them all and loved them, though I thought that the author dragged the series out a bit.
