In the distant future, the world has been destroyed. Some companies had the foresight to create safe havens. Kroz Enterprises created Central City. It is there that the Nartana brothers solve cases for President Kroz to keep the place running smoothly...despite the actions of the inhabitants.
Each case is published individually as an eBook. Seven cases make up one collection, which are published both as eBooks and Paperbacks at Lulu. There are additional parts to the overall story about Central City contained in the collections too.
