What will the world look like 50 years from now? The prospect is grim, particularly in comparison to what was imagined 50 years ago when technology promised greater prosperity, health and happiness. The view that David Morse presents in his novel The Iron Bridge is so bleak that one woman from the year 2043 agrees to venture back in time, her mission being to alter the course of the Industrial Revolution. The plot is so imaginatively constructed that the reader is left wondering whether the heroine, Maggie Foster, was successful in her mission. Maggie's grandmother, one of the baby boomers, is the link to our age. Her philosophy is summed up in the advice that she gives Maggie: "Believe in yourself." The novel tests the truth and limits of such a stance. A stranger in a 1773 Shropshire village, Maggie must work alone on her mission and yet discover who she is through interaction with the people she meets. The Iron Bridge is both a first-rate novel of ideas and an absorbing narrative because of the finely drawn characters and the fully realized historical setting. While I was reading it, I could hardly put the book down; since finishing it, I keep thinking about the questions it raises. It's the kind of book that makes you want to have your friends read it so you can talk with them about it.
