Flush, by Carl Hiaasen

 This book is a good book about saving the environment. It's realistic fiction. It has a grabbing law aspect which included issuing subpoenas house arrest and gathering evidence to bring bad guys to court. I didn't expect certain characters to end up being bad. I highly recommend this book for third through fifth grade reading levels. This is a great website for the author: http://www.carlhiaasen.com/index.shtml
