So much is owed to our brave American service members, who place their lives on the line to protect and defend the United States. However, many also face persecution for their religious convictions within the confines of military service branches.

This cause runs deep for author JP Ronald and powers his new naval, historical novel, SSN Command Into the Crucible, which takes place during the Korean and Cold Wars. Lieutenant Commander Daniel O'Kean, a CIA agent trained in maritime special operations, is recruited by the United States Navy for a covert mission to infiltrate South Korea's Pusan seaport and spy on the secret missions of the Chinese and Russians.

He is assisted by submarine captain Timothy Blake to help give the US Navy a leg up against the Communist nations. The book also focuses on the faiths of American soldiers and the need for God to lead America once again.
