Two Worlds Become One

In the 'Two Worlds Become One,' two black holes appear above the ship and release Jackie, Jonah, and Natalie. Jackie and Natalie can't stand each other, one bit. They consistently fight each other until someone stops them. Three main characters end up travelling the world and meeting new species with the captain of the ship.

Note: Read 'Opposite Attract: Demon And Human' and 'Half Human, Half Vampire' before this one. This one is the sequel of them.
