America: When the public launching of the country's most sophisticated nuclear submarine is followed by a violent hijacking, only Admiral Jake Grafton stands between the deadly cargo and its intended target: the nation's capital.

Liberty: Liberty continues the adventures of Adm. Jack Grafton as he pursues major malefactors. This time, a rogue Russian general has sold nuclear warheads to a Mideastern anti-American terrorist best known for "hacking some tourists to death with a machete" in Egypt. Grafton must identify and locate the terrorist and his cronies before he detonates the weapons in the U.S. The action moves from central Russia and Suez to the American east coast.
