Ashfall and Ashen Winter

We have both of these titles in the library. Ashfall starts with a massive volcanic eruption in the Yellowstone National Park in America. This created massive devastation and loss of life in several American states. Alex, the main protaganist, is separated from his family and sets off to find them amidst the chaos around him. Anarchy rules with corruption not far behind as the survivors attempt to stay alive in a totally altered world. This trilogy contains some fairly gruesome parts and is more suitable for seniors. What struck me most about these books is that living in a volcanic region as we do how would we behave in similar circumstances. I'm waiting for the final in the trilogy now.
