Imagine a world where everyone over the age of 15 disappears, to find yourself trapped inside a sphere 20 miles in diameter surrounded by a shimmering impassable wall. This world is Gone. An exhilarating, fast moving, compulsive read. Kids develop powers, animals mutate and everyone is in survival mode. They face horror, starvation, plague and finally permanent darkness. This series is brilliantly conceived and inventive. Each book is consistently good, pact and exciting. Young adult fiction at its best.
