Summer Reading

I need your help!  My DOU (dear old uncle, for those of you not in the loop) gifted us a Kindle as a wedding/anniversary present and I need book suggestions!  I'm really looking forward to so many reading options on the metro, by the pool, and for all the travel I'll be doing this summer and fall.  

SO!  Please leave reading suggestions in the comments.  They can be old or new titles.  Popular or obscure.  I just need direction.

Now, off to write this paper so I'll be able to read for enjoyment when I'm done!
