I read this on my way to the AALL conference in Portland OR. This book is set in Portland, although it's just a backdrop and doesn't play into the story much.George (GTO) Olson's wife Francesca and daughter Abby (?) disappear while he's out walking the dog, leaving a note that they have left (without a car, luggage, cash, credit). George fumbles through the first days and starts acting increasingly bizarre, and ultimately slips into a kind of psychotic break. At first intriguing, then too much in the middle, and then the end redeems the book again. There's a long extended theory about the number 42 which comes from the Hitchhiker's Guide to the Galaxy as the answer to the universe.
