The Convergence That Held

The Convergence That Held by Tabitha S. Is about two souls Bobby and Littlebit who are destined to be together, but in alternate universes. The prophecy says that two souls cannot stay in the same world, one must choose to return to their own world or the universe will be destroyed . Will one of them choose to go back to their own world? Or because their souls love is so strong will they rewrite the prophecy (rewrite the stars.?) And change the universe forever .?
