Let me just tell you, fungus scares me. I do not want it on my pizza. It grows in dark, moist corners and feeds off compost. Yuck! Let's just say fungus plays a big role in this book and each page will keep you in suspense as well as go "yuck". I loved it, really. It reminded me of the first Dean Koontz book I read that got me hooked: "The Taking". Same kind of post-apocalyptic feel with just as much of a human-less, fungus-filled environment. Enjoy! And stay away from the mushrooms!
