Too many books?

I tend to read too many books at a time, sometimes.  I have six going right now, which is clearly too many:

E.I. Wong, Poet Robot
Kevin Wignal, A Death in Sweden
David Weber, On Basilisk Station
David Mitchell, Ghostwritten
Lisa Randall, Dark Matter and the Dinosaurs
Os Guinness, Fool’s Talk

I’m a little stalled on Guinness and Randall, but I’ll finish.

I promise I will give you some thoughts on Adam Roberts, The Thing Itself, and Sarah Hepola, Blackout: Remembering the Things I Drank to Forget, each of which were fascinating (but in very different ways).
