COLIGO: Book #1, The UNITAS Series

There can only be one winner in the ruthless game to control The City.
The players include: an intelligent female scientist with a life-saving discovery, a detective seeking justice from an uncaught serial killer, an irresponsible time traveler wishing he belonged, a powerful android leader seeking retribution for her kind, and a governor unsure if he's the good guy or the bad guy.
Who will succeed? Or will a mysterious, villainous presence stop them all?
