John Scalzi is a famous author of science fiction, and his books often explore a universe where old men are genetically modified and made young in order to serve as soldiers in outer space. Part of the process turns these formerly old men into youthful, agile, and green not-quite humans. The old people young thing, sure. The outer space battles against countless aliens, sure. The green skin, alright. Where Scalzi went over the line and shattered my suspension of disbelief was when he stated that the Cubs had won the World Series. Get the hell off my book shelf! Anyway, fair to good read besides that; however, if you wanted a novel, keep looking. This is a book of intertwined shorts.
