Just finished "Parasite Rex" by Carl Zimmer. Fantastic book if a little creepy at times. Zimmer is an excellent science writer and this book about parasites (who apparently make up the majority of species) is written for the layman. The author has a blog I like and one of my favorite features is
this. He asked one day in his blog if anyone had a science tattoo and the pictures started coming in so he set up a space for them and adds a new one every Friday.
Now I'm on to "The Road" by Cormac McCarthy. Pretty dark as you'd expect from him.
