‘Bot War (https://www.smashwords.com/books/view/677836) In which the problems of Puppeteer have not been addressed. The government is still essentially bankrupt, but Islamic terrorists determined for revenge for what happened in their homeland take control of the latest AI war machines.
Troubles (https://www.smashwords.com/books/view/174203) The world is recovering from a state of anarchy. There is money to be made, and opposition to kill. Law and order is privatized, and those with money have a huge advantage.
