Assemblers of Infinity
Kevin J. Anderson
 It is the 21st century. Earth's space program is thriving, with a colony in place on the Moon. And then an incredible discovery is made on the lunar farside. A massive structure is being erected by living machines—microscopically small, intelligent, unstoppable, consuming whatever they touch. All who come near them die horribly. Meanwhile, the mysterious structure continues to grow, expand, take shape. And its creators begin to multiply. Is this the first strike in an alien invasion from the stars? Or has human nanotechnology experimentation gone awry, triggering an unexpected infestation? As riots rage across a panicked Earth, scientists scramble to learn the truth before humanity’s home is engulfed by the voracious machines.
