Query: The means were not worth the end

Nelson DeMille and his great character, John Corey, are fun to read but the ending to this book was so disappointing that I would not recommmend it. Mr. DeMille, you can do better! You should have just picked a version of the "rocket theory" and told that story, maybe in a parallel storyline way you did with Asad Khalil in the much better book, Lion's Game.I love John Corey's humor, wit, and sleuthing skills, but don't write another book with him unless you have a good end in mind!Thanks!
