United Worlds Authority eBook 10 is the continuation of a 12 episode series. The Enemy, a biological weapon leftover from a two hundred year war between now extinct races, has been ravaging the Known Galaxy ever since. However, the tide of war has begun to swing against them because of the Anrypan Imperial Republic's constantly improving technology and is now vastly superior than the Enemy's. The Republic is a member of the Authority and both are gradually forcing the Enemy back from where they came, the mini-galaxy Sagittarius. Yet another opponent has appeared near the Galactic Core called the Hydramae. Neither the Republic or Authority can fight a two front war. The Royal Executive, RE and leader of the Republic, sets up a ploy to get these both foes to fight each other and become exhausted. The RE, Angelica the Third's, plan goes amiss and she needs to prevent the Enemy from exterminating the Hydramae and using its resources against her. Hopefully her scientists can finish developing a new weapon, Twin Event Horizon, first used against the Enemy and then it becomes other opponents turn. It seems Angelica has more headaches than solutions.
