Wide Awake is a very widely known Twilight Fan Fiction by the author Angstgodess003.
With an amazing mixture of Angst, Comedy, and Wit, it is more than worthy of being published into it's own book.
It is highly suggested among many of the Twilight Fandom.
Summary: Edward and Bella have dark pasts that leave them severely emotionally scarred, with nightmares that force them to stay awake. They meet and begin to form a bond during the night hours. All Human
The story has been discontinued on FnaFiction.net but is still being written on the Authors LiveJournal:
Some might say that Wide Awake is better than Twilight itself. Even if you don't like Twilight, read it.
