Query: Great, edge of your seat mystery

My opinion it was the type of book where you, the reader, could put yourself in the main character's shoes and go through the same realistic adventures, feelings and emotions she was. This book was a good mystery. It had me going back and forth through out the book, to try to figure out the killer. This book had a suprise ending, that was a shock. An ending I never would have suspected. This is a good book also because it makes the reader in my opinion, become a detective themselves. Also if you can figure out the ending before you read it, your lucky because it is totally unexpected.
