DESC: After crashing his truck and falling into a 14-day coma, Mark Schluter wakes up with Capgras Syndrome, and believes that his sister Karin has been replaced by an imposter. Devastated, Karin calls in a renowned neurologist to help. Meanwhile Schluter follows his sole lead, an anonymous note, in the hopes it will reveal the mystery of his condition and his inexplicable accident. Capgras Syndrome is a division of a person's intellectual and emotional understanding, but in his ninth novel Richard Powers once again proves he is equally adept at both sides of the equation: THE ECHO MAKER is full of rich ideas and powerful humanity. It is captivating and sorrowful.
