A New York Times Notable Book for 1998 <P>Critical acclaim for Lawrence Wright's <P>A Rhone-Poulenc Science Prize Finalist <P>"This is a book about far more than twins: it is about what twins can tell us about ourselves."&mdash; The New York Times <P>"With plenty of amazing stories about the similarities and differences of twins, Wright respectfully shows, too, how their special circumstance in life challenges our notions of individuality. A truly fascinating but sometimes spooky (Mengele's experiments with twins at Auschwitz figure among Wright's examples) study."&mdash; American Library Association <P>"Like so much of Wright's work, this book is a pleasure to read. Because he writes so well, without pushing a particular point of view, he soon has you pondering questions you have tended to comfortably ignore."&mdash; Austin American-Statesman <P>"Informative and entertaining . . . a provocative subject well considered by a talented journalist."&mdash; Kirkus Reviews
