Query: Wolf Rider

I think Wolf Rider is a great book with a lot of action and suspense. It has a really good plot and a fantastic ending. It is about a boy named Andy who gets a phone call from a guy who says he killed a girl named Nina Klemmer. He says his name is Zeke. Andy calls the police but they don't believe him. No one believes him. It will keep you up all night until you finish it. I definitely give this book a 5 star rating because it describes the characters and settings really well. I think this book is good for 8 to 13 year olds. So go out and get the book and start reading it now!!!!!
