Ratner's Star

One of DeLillo's first novels, Ratner's Star  follows Billy, the genius adolescent, who is recruited to live in obscurity, underground, as he tries to help a panel of estranged, demented, and yet lovable scientists communicate with beings from outer space. It is a mix of quirky humor, science, mathematical theories, as well as the complex emotional distance and sadness people feel. Ratner's Star demonstrates both the thematic and prosaic muscularity that typifies DeLillo's later and more recent works, like The Names (which is also available in Vintage Contemporaries).  

"A mind-expanding trip to the finish line, and full of wit and slapstick as well.... The areas of knowledge central to Ratner's Star are astronomy and mathematics. DeLillo develops them brilliantly, so that the expert can wallow while even the layman can splash happily in the shallows or pick up pebbles on the shore."--The Washington Post Book World
