Strike Zone (Star Trek: The Next Generation, Book 5)

Deep in the uncharted regions of our galaxy, the Kreel, a primitive, warlike race have stumbled upon weapons powerful beyond their wildest imagination. The Kreel have used those weapons to attack their most bitter enemies, the Klingons. Captain Jean-Luc Picard and the crew of the USS Enterprise are called in to mediate the dispute by ferrying diplomatic teams from the two warring races to the source of their conflict, the mysterious planet where the weapons were discovered in an attempt to find a peaceful solution to the conflict, and discover the origins of the super-powerful weapons.
