The "Starship Enterprise(TM) " has embarked on its most ambitious assignment yet: to lead a courageous band of settlers to a far-off planet, to defend the fragile colony from alien threats, and to unravel the mysteries of a brand-new Earth! Belle Terre A six-month distance from the Federation, the planet Belle Terre offers a new life to more than 30,000 families, pioneers, scientists, expatriates, go-getters, loners, and entrepreneurs, all under the watchful eye of Captain Kirk and his crew. But the would-be colonists have barely settled in the untamed wilderness of their new home when Spock makes a startling discovery: not only does the planet's moons contain a rare ore of almost inestimable value, that same moon is also violently unstable. Within months, it will inevitably explode -- destroying all life on Belle Terre!
