The end is here. In the fifth and final Two Worlds novel, Rii, a heroic knight, and J997, a law enforcement robot, must work separately and together to stop the reunification process that is bringing the two worlds together. At stake are the lives of the billions of innocent people on both worlds, including Rii's siblings and J997's fellow law enforcement officers, who will not survive the forcible reunification of the worlds. But with Reunification's leader and his followers blocking their every step, Rii and J997 must use their strength, cunning, and intelligence to save the two worlds from certain doom. And if they fail, then the consequences will be truly apocalyptic.
