some book covers don't make that much sense until you read the book. in this book, there is a disease that when you get it you detonate and blood goes everywhere, so that the disease can spread. this is an amazon link where you can see the cover
its a really simple deisign, but looks really good
I just finished "This Mortal Coil" by Emily Suvada. You can find the description of it here:

It's my second favorite book of all time.
