Query: Review of Mr. Rush's AP Environmental Science Class

This dramatic account of this toxic dinoflaggellate is factual and descriptive. The beginning is well-paced and keeps the reader's attention. However, toward the middle of the book the plot becomes repetitive and more politically based. It was frustrating for the reader to read all the processes of funding and the failures. The book informs the public of a topic that is kept secret by the government. The author researched the data well and presented the information in an interesting way including a cliff-hanger to end each chapter. Overall, this book is recommended for an interesting read into the danger that lurks the coastal waters of North Carolina.
