Silent Thunder

After Silent Thunder, a Russian nuclear submarine, is purchased by the U.S. government, Hannah Bryson is hired to make sure it is safe for use as a maritime museum. However, American and Russian operatives have a specific interest in the submarine so when Hannah's brother makes an unusual discovery, a deadly attack follows. One of the Russians, Nicolas Kirov, and Hannah eventually team up to find the killer and uncover the mystery surrounding the discovery.

This was another library sale find and would have been a good international thriller read. Since the book was mainstream and the story revolved around submarine sailors and espionage, I didn't expect it to be profanity-free; however, the use of the Lord's name as an expletive sprinkled throughout the book was offensive and unnecessary.
