Discover the beginnings of Klingon’s most sacred holiday in this thrilling entry in the bestselling Star Trekseries. Signi Beta is an M-class planet ideal for farming. The Federation wants it, but the Klingon Empire has the stronger claim. Captain Kirk of the USS Enterprise hates to lose the planet, especially to his old adversary, Commander Kor. Their mutual antagonism turns into an uneasy alliance, however, when yet another alien fleet attacks both the Klingons and the USS Enterprise. Now Kirk and Kor must rely on each other’s honor—or none of them may survive to wage their war again.
