THE WRIST IS POISED

So what is it with the really heavy books at the moment? Or is it just that I am having a "reading things in hardback" sort of month? 

I'm not complaining per se, but the only problem is that after both  "The Northern Clemency" and "The Rest is Noise" my arm aches. 

What if I get tennis elbow and then can only read really tiny paperbacks?
