The Loaded Bookshelf

I love planning books to take on vacation, though whether or not I get around to reading them is a different story.  I'm about to embark on my summer vacation for July 4th, and have chosen these books to accompany me on my travels:

A FIERCE RADIANCE -- this is a pick for my July book club meeting (it's my pick, so I really should make sure to read it).  A historical work about a female reporter covering the invention of penicillin, I'm hoping this will have a great period feel.

NIGHTSHIFTED -- A nurse works on a hospital ward where the patients aren't quite . . . natural.  I didn't think I'd get this in from the library until after vacation, but it's waiting for me now, so I'll pick this up as my "guilty fun" read.

HAPPIER AT HOME -- I loved Rubin's first book THE HAPPINESS PROJECT.  Though I haven't undertaken a happiness project of my own, I find her insights and examples useful, and think I've drawn some benefit from reading her books even if I haven't put what I've learned into organized practice.  Also, I sometimes find it easier to read non-fiction on airplanes than fiction.

What books are you taking on vacay?
