Crisis on Centaurus — Brad Ferguson

Massive computer malfunctions are plaguing the Enterprise when Kirk suddenly receives a shocking message from Star Fleet Command: Centaurus has been bombed and annihilated; thousands are dead. Give whatever help you can. Centaurus is a beautiful, peaceful planet, home to many humans--including McCoy's daughter Joanna.

The crew risks beaming down to investigate. But Kirk is thrown into a deadly struggle between violent enemy terrorists and vengeful Centaurians. Now Lt. Uhura, left alone in command, must jeopardize the crippled Enterprise to save Centaurus, Kirk--and Joanna McCoy!
