The writer-producer who created Mr. Spock and all the other Star Trek characters – who invented the starship Enterprise, who gave the show its look, its ideals – puts it all together again here in his first Star Trek novel! Their first five-year mission is over. Kirk, Spock, McCoy, Scotty, all the crew have scattered to other jobs or other lives. Now they are together again on a fabulously refitted USS Enterprise as an incredibly destructive power threatens Earth and the Human race.

THE UNIVERSE HAS LESS THAN A CENTURY LEFT… UNLESS SPOCK CAN CHANGE HISTORY! The Enterprise is summoned to transport a dangerous criminal from starbase prison to a rehabilitation center: brilliant physicist, Dr. Georges Mordreaux, accused of promising to send people back in time – then killing them instead.

Mordreaux's experiments have thrown the entire universe into a deadly time warp. Spock is fighting time … and the universe is closing in on itself with the relentless squeeze of … THE ENTROPY EFFECT
