The Klingon Gambit

When Captain Kirk and his crew are ordered to Alnath II to challenge the deadliest Klingon starship Terror, they're ready for anything - or so they think. But the defenseless Vulcan crew of a Federation science ship has been wiped out. The remaining member of the Alnath II mission have discovered a fabulous ancient city, but their report doesn't make sense. The Klingon battlecruiser has the Enterprise in its sights, and ready to destroy it. But Captain Kirk can't seem to make decisions. Spock has started to throw temper tantrums. And Chekov has disobeyed vital orders. The crew of the Enterprise are losing their minds... one by one... all victims of... The Klingon Gambit.
