So, this is a crossover of Twilight and Matrix.
So Bella is like Neo, just a bit better. Neo and Trinity are still alive. No Smiths, but the Twins are still out and about. Link Zee Niobe Morpheus Neo Trinity and Bella are all part of the Nebuchadnezzar's crew. By some freak accident, the crew are all immortal.
While the planet is being rebuilt, everyone is staying in the Matrix unaware. Bella is almost constantly in the Matrix looking for anybody who knew or had a suspicion about it not being real, or things not being quite right so they can help rebuild the planet, if they want to of course.
Her and Morpheus have a semi permanent residence in Forks. 'Cause Morpheus is known as a terrorist he's Chief Charlie Swan, Bella's dad.
They've just moved there and schools just coming out for the end of the day when our story begins.
That's about all I can think of.
