Death Note Fanfic

Sera is an unusual girl. With blue hair and blood red eyes things can get out of hand. When she's abandoned at 1 month old and a Death Note is dropped on her head and a shinigami appears, that doesn't help either. She refuses at first, but then her eyes are opened up to the world. She starts killing criminals secretly without a trace and people think nothing of it, but when Kira comes into play her plans are threatened. If Kira's found out, then so is she. When Kira meets her he must kill her, but will he be able to with something new forming?
