Fresh from the Academy, Ensign Paul Sinclair has been assigned to the warship USS Michaelson, whose mission is to stop any foreign vessels from violating U.S. sovereign space. When Captain Peter Wakeman mistakenly destroys a civilian science ship perceived as hostile, Sinclair must testify against Wakeman at a court-martial hearing. But Sinclair believes that the severity of the charges against the captain are unjust--and becomes a witness for the defense...

In John G. Hemry's terrific military science fiction series, a young officer risks everything in his fight for justice . . . Lieutenant Junior Grade Paul Sinclair must adjust to his new position on the warship USS Michaelson--juggling his Legal Officer responsibilities and his personal life, as his relationship with girlfriend Jen Shen intensifies. When an explosion takes out most of Forward Engineering, Sinclair leads the effort to extinguish the fire. He's practically a hero. But when Captain Shen, Jen’s father, is brought in to conduct an investigation, it seems that he’s gunning for his daughter’s suitor. Soon Sinclair uncovers evidence that points to a cover-up—involving a rising star in the officer corps. His evidence is circumstantial, and the suspect is the son of a powerful vice admiral.
