needed: a good book

Since I'm done with textbook reading (except for when I'm feeling extra nerdy & wanting to refresh my clinical and research knowledge) I need a good book! I feel like whenever I have no time for leisure reading I always have a list of books I want to dive into.  But now that I have the time to read for fun I am at a loss for what to read! I have a B&N gift card burning a hole in my wallet just begging to be spent.  Thoughts, suggestions?
