Query: A Page-Turning Techno Thriller

This is a complex, well-developed thriller that builds to a nail-biting resolution. What if Castro had kept one of the missiles of October? What if it were a threat to the U.S. today? High tech investigation and FBI field agent effort blend in a frantic search to stop a nuclear event. This book's excellent core idea is developed and executed with intelligence and a deft attention to detail. Hopefully an e-edition of this novel will be coming soon.
