This book seemed to have all the ingredients and starts out great - absorbing characters - zippy narrative - a cross-country roadtrip. Unfortunately, it runs out of gas halfway. In the end, even a triple shot of Starbucks couldn't revive this braindead reverie. Sometimes magazine articles -- from which this was expanded -- are only a few pages long for a reason.
