Query: This book is a mystery book.

This book is a book about a mystery. Frank and Joe, the Hardys, go through a lot of problems. They find a bomb in a locker. Joe takes it out and throws it away in time. It exploded but nothing was ruined. The Hardys found a silver bullet in their door. It's the only bullet that can kill a werewolf. They want to go to the Adirondack's with their friend Chet. He doesn't know that are going to find the werewolf.Something that I don't like about the book is it has words that are hard to pronounce. It has pictures that are in black and white. The book has 20 scary chapters and great laughs. If you read this book I'd say " Reader beware you're in for a scare ! " Nothing better than a werewolf that meets you face to face. I recommend this book for older people because it has hard words and it's a mystery.
