"Dr. Spencer Brownfield, an elderly, disgraced former professor, believes that for thirty years he has been the sole person standing between New York City and complete cataclysmic collapse via his ''adjustments'' - tiny, Butterfly-Effect-like changes he makes to the city.

Can Wilson take what little he''s learned and save the city in time?" -- page [4] of cover.
