Line of Fire (Star Trek: The Next Generation - Starfleet Academy, Book 2)

Mysterious space raiders are threatening the joint Federation-Klingon colony on the remote planet of Dantar, and pitting the two sides against each other. Worf and his fellow first year cadets -- Zak, Tania, Soleta, and Mark -- have accompanied their teacher to observe the negotiation process, but soon find themselves in the middle of an intergalactic dispute. For just as Worf and the other cadets arrive, they discover the Klingon Empire has sent its own diplomatic team, including Klingon cadets, to investigate the attacks. As the cadets from Starfleet AcademyTM come face to face with their Klingon counterparts, tensions quickly mount as each side accuses the other of staging the raids. And while a deadly space battle rages overhead, Worf faces his ultimate test as his Klingon heritage and future in Starfleet collide.
