I take issue with the question in the title. It should be: 'which book are you reading?'.
Likewise - I'm not always in the mood for froth or heavy, either, so I've got:
Phillip Roth's American Pastoral,
Neil Stephenson's Interface,
Neil Shubin's Your Inner Fish (evolutionary biology, nothing more weird),
Karen Armstrong's The Great Transformation (history of pre-Christian religion - fascinating even to an atheist and much recommended)
Peter Parson's City of the Sharp-nosed Fish (archaeology)
all on the go (and a Michael Dibdin Aurelius Zen book in reserve for when I finish Interface)
