Query: This book is astounding and action packed.

This book is about a girl in New England that sees her face on a milk carton that she took from her friend. She is allergic to milk so at first her friends think that it's just the lactose kicking in, causing her to see her face. Her best friend Reeve understands until the two start dating and he tries to force her to get help. This book is a horrifying mystery. This would be awful if it happened to anyone. I liked this book because it is exciting and unpredictable.
