Crisis on Centaurus is a 1986 Star Trek: The Original Series novel written by Brad Ferguson.

Millions are dead; because of a computer malfunction, the planetary defense system is preventing any rescue ships from approaching the planet.

Despite an emergency do-not-approach warning (known as Code 7-10, which went unheard), the first three relief ships, carrying hundreds of medical personnel, are destroyed by ground-to-air missiles as they assumed standard orbit.

The USS Enterprise has been sent to assess the situation and offer what relief they can, but they are in need of help themselves as the ship is falling apart around them due to an unexplainable massive computer malfunction of their own; the transporter is made inoperable by the antimatter's residual tachyon radiation.

On seeing the names 'Garrovick' and 'Farragut' on a map, Commander Spock correctly surmises where Kirk is hiding, and a scan from orbit reveals an army of government hovercars flitting around the cabin.
