Cold shot a novel

The USS Vicksburg is returning home when the crew comes upon a lifeboat bearing a dead Somali pirate who shows signs of torture. Red Cell analysts Kyra Stryker and Jonathan Burke trace the dead man back to an Iranian ship currently bound for Venezuela-- and the ship appears to have dangerous, radioactive cargo on board. The Iranians' plan quickly becomes clear: they're building a nuclear bomb in politically unstable Venezuela, away from the UN's prying eyes. Can Stryker and Burke stop the Iranians before it's too late?
