THE GREATEST DANGER HIDES IN THE DEPTHS OF DECEIT. In a Murmansk hotel, a U.S. naval officer is found dead along with a young Russian sailor in what is labeled a murder/suicide — but American navy commander Jake Scott thinks otherwise. Assigned to escort the dead officer's body back to the United States, Scott discovers that his predecessor had uncovered a secret that cost him his life — and may cost Scott even more.Aided by alluring weapons expert Alexandra Thorne, Jake uncovers a conspiracy of betrayal, terror, and vengeance intended to target a tense summit meeting of the American and Russian presidents. Taking the helm of a Russian sub, Scott must race against the clock — and face off against an unseen enemy under the waves — if he hopes to prevent a nuclear strike that could ignite World War III.
