From the bestselling author of Einstein's Dreams comes this harrowing tale of one man's struggle to cope in a wired world, even as his own biological wiring short-circuits. As Boston's Red Line shuttles Bill Chalmers to work one summer morning, something extraordinary happens. Suddenly, he can't remember which stop is his, where he works, or even who he is. The only thing he can remember is his corporate motto: the maximum information in the minimum time.
Bill's memory returns, but a strange numbness afflicts him. As he attempts to find a diagnosis for his deteriorating illness, he descends into a nightmarish tangle of inconclusive results, his company's manic frenzy, and his family's disbelief. Ultimately, Bill discovers that he is fighting not just for his body but also for his soul.
