Help me find this story?

I know we're not supposed to do this but I just must know what this story is called and who it is by before I lose my mind!

Okay! It is set after Edward leaves in New Moon. It is the only New Moon story I have really liked so far.

Bella gets attacked by Laurent and the wolves are too late to save her. Laurent knocks her down trying to get away from the wolves and she hits her head on a rock or something and loses her memory. She doesn't remember Edward or any of the Cullens.

Then she goes to college and the Cullens are there. Edward lectures her about her motorcycle and she asks Alice if he is an idiot savant.

Umm, let me think here… she gets a tumor caused by her fall then she ends up remembering Edward but doesn't go back to him and that's where I left off…

It's a really great, great story! And I really wanna see where it goes but can't, for the life of me! Remember what it is called or who it is by! Please help?
