Query: Pass on this one

I finished this book and pretty much immediately forgot what it was about. Carboard characters and a lack of energy make this Sheldon novel one to pass on. Usually I read Sheldon on an airplane-- guaranteed to finish it before I land. And usually his stories are fun diversions. But his latest lacks his better touches-- a fast, twisty-curvy plot.
