Hurray! An intelligently-written book that was a joy to read.
Paul O'Rourke is a dentist, successful in his profession and miserable/clueless in his personal life. Then, someone creates a website in his name, followed by a Twitter and a Facebook account. O'Rourke starts to communicate with the impostor, to vent his anger. After awhile the communication leads him to places within himself.
The book is a dark comedy. O'Rourke's life is pratfalls in a room in which the lights have permanently gone out. The God theme runs throughout the book, first as O'Rourke's personal blatant atheism. Then, O'Rourke's nemesis tells him both he and O'Rourke are descendants of a mythical peoples, the Ulms, who have been instructed by God to doubt his existence.
I loved O'Rourke's bumbling journey, in all its fits and starts. I was sad to see the book end.
