Picture in your mind the typical zombie – dead, slow, rotting, and stupid. The author of Silver goes the opposite way with the idea of the undead. These terrifying computer – like creatures are very fast, very advanced, and with their hive mind, extremely smart. When a group of boys at a boarding school discover a beetle that looks to be made of metal, they are excited that they may have found a new species. Then it bites one of them, and in a few hours less than fifty students are still alive - and human.
