"The city is at a breaking point. Living space is running out. Those in power are forced to execute a desperate measure - introduce a poison to wipe out a huge part of the population. This is no ordinary city, however. Overrun takes the reader into the heart of their own computer. Citizens are files. There are .xls business people, sexy .jpegs, hip musician .mp4s. The space which is running out is memory - the poison a computer virus. Political intrigue and epic action scenes take place inside this brilliantly crafted world as we follow a group of friends, forgotten computer game heroes, as they fight their way through the virus infection which is transforming their fellow citizens into memory sucking zombies."
