George Mahoney suspects he is getting a little stale at redesigning refrigerators, after fourteen years in the same job. With the arrival of his new office mate, Niagara Spense, George is forced to re-evaluate everything in his life from love and family, to science itself. Obsessed by the six feet tall Niagara, the very foundations of George's belief in facts and the physical world are shaken when she reveals that she is on an incredible quest for electrical evidence of life after death—"audible fossils" she calls them. As Niagara Spense seeks the dead, and George seeks her, everything suddenly becomes possible in a novel that makes engineering funny, and mixes the world of icemakers and buttersofteners with the miraculous.
