The Jedi Council has sent Depa Billaba - Mace’s former Padawan and fellow Council member - to Haruun Kal to train the local tribesmen as a guerrilla resistance force. But now the Separatists have pulled back, and Depa has not returned. The only clue to her disappearance is a cryptic recording left at the scene of a brutal massacre: a recording that hints of madness and murder and the darkness in the jungle...a recording in Depa’s own voice. Mace Windu trained Depa. Only he can find her. Only he can learn what has changed her. Only he can stop her. He will leave behind the Republic he serves, the civilization he believes in, everything but his passion for peace and his devotion to his former Padawan. And he will learn the terrible price that must be paid when keepers of the peace are forced to make war....

    The U.S.S. Enterprise, under the command of Captain Christopher Pike, responds. Starbase 18 lies in ruin. There are no survivors. And there is no clue as to who is responsible for the attack, until Captain Pike’s brilliant science officer discovers a means of retrieving parts of the station’s log. Lieutenant Spock has detected signs of a unique energy signature, one that he believes is Klingon. There are unsubstantiated reports that the Klingon Empire has made a technological leap forward and created a cloaking device—code-named Black Snow Seven—that can shield their ships from even the most advanced sensors. The destruction of the base and the unique energy signature that remains prove that the Empire has succeeded. For generations the Orions have been known as pirates,operating at the margins, outside of legal conventions. A proud and powerful race, the Orions were once a major force in the sector, and they have been using the tension between the Klingon Empire and the Federation to rebuild their power. Captain Pike is charged with trying to foster cooperation between the Orions and the Federation. A distress call from an Orion vessel offers him the perfect opportunity. But the Orion ship lies in disputed space long claimed by the Klingon Empire, and crossing it could be the spark that sets off an interstellar war.
