I'm reading a good book, slowly.

I'm reading the book "Unbroken" by Laura Hillenbrand and I highly recommend it. It's the true story of WWII airmen stranded on a life raft after their plane crashes in the Pacific and then captured by the Japanese.  I've seen the movie and I thought it was good but it doesn't begin to have the emotional impact of the book.  The problem is I only seem to be able to read it in small chunks.  Usually, when I'm into a good book I can spend hours reading but not with this one.  It's just too intense.  That doesn't mean I won't finish it, it may just take a while longer than usual.
