Moonseed / Stephen Baxter

Stephen Baxter, the much-lauded author of Voyage and Titan, has been praised as a sci-fi writer who gets the science right. This rigor and research are clearly evident in Moonseed, a tale with high-energy physics and space-travel technology in starring roles. It's Baxter's boyish enthusiasm for science--especially space travel--that makes Moonseed so involving.

A world-class disaster epic worthy of any Saturday matinee, Moonseed opens with the spectacular, explosive death of Venus, an event requiring energy a thousand billion times the world's nuclear arsenal. As the radioactive blast from the late Venus reaches Earth, scientists scramble to attribute a cause, with massless black holes and elementary particles the size of bacteria pointing towards some sort of superstring as the smoking gun. The pace quickens when the substance that may have caused the demise of Venus is accidentally introduced to Earth. This substance, dubbed moonseed, acts as a geological lubricant: processes that normally take millions of years occur in mere months with moonseed in the picture. Once Scotland and the state of Washington get gobbled up by this rock-eating, 10th-dimensional nano-lifeform, all hell breaks loose and the search turns towards finding safe refuge for humanity on the Moon. The book's second half is a seat-of-your-pants, what-if exploration of space travel and terraforming.

An over-the-top doomsday yarn by some measures, Moonseed keeps your feet on the ground with good science, good characters, and a good story. --Paul Hughes
