A war between China and America is a favorite subject of armchair military analysts. Why would it happen? How would it play out? Authors have written thousands of pages online and off trying to answer these questions.

That's why "Ghost Fleet," a new novel by national security analysts August Cole and P.W. Singer, is fascinating. The book, set in the near future, is an account of a war between China and the United States written by two men whose day jobs are studying conflict and making policy recommendations.

If anyone could get this scenario right, it's these two military experts. Though it is fiction, the authors have taken great pains to keep their storytelling realistic.
