In an era of genetic engineering, Lieutenant Henry Gallant is the only Natural (non-genetically enhanced) officer left in the fleet. Many of his superiors, including rival Anton Neumann, have expressed concern he is not up to the challenge. However, his unique mental abilities have proven essential to the defense of the United Planets in its fight against the Titan invaders. Serving on the first FTL prototype, the Intrepid, on its maiden voyage to Tau Ceti, Gallant finds a lost colony on the planet Elysium. Cyrus Wolfe and his son, manipulate planet politics against the democratic opposition led by James Hepburn and his granddaughter Alaina. Wolfe has allied himself with an ancient Artificial Intelligence which had lain dormant on the planet for millennia, but is now willing to protect the colonists against the Titans. With Alaina’s help, Gallant discovers the ancient AI has a sinister ulterior motive and he matches his unique and exceptional mind against the complexity of machine intelligence to escape the ultimate trap and prevent the extermination of humanity. In Lieutenant Henry Gallant, one man pits the naked human mind against the perspicacity of machine intelligence.
