Star Trek: Mere Anarchy

Mestiko: a world on the brink of interstellar space travel,and under covert Federation observation. When a rogue pulsar sweeps through their star system, threatening to destroy all life on their planet, the Federation mounts a desperate effort to protect the planet from annihilation. Under the command of James T. Kirk, the Starship Enterprise, is able to mitigate some of the damage, but the world's surface is still devastated with appalling loss of life. Over the next thirty years, the Enterprise and its crew revisit Mestiko, whether to keep them from falling prey to the machinations of the Klingon Empire or to deliver a new method of replenishing the planet's ozone, through trials and tribulations, hardship and strife, and love and death.
