I am currently writing a Land Before Time story, called Out of the Shadows. It's also at FF.Net but it is rated M, and dark and violent. Not something you should let kids read. It's about Chomper betraying the gang and trying to take over the valley with other sharpteeth, but something else is controlling everything. There's a lot of twists and turns in the fanfic, and appearances of not only official, but fanmade characters.
Yes, my story is the other M rated story that Cyberlizard mentioned. So yeah I do have major character deaths, however, I do plan on a special ending that'll fix all that. ^^
Afterwards, if I don't decide to write my first book (yes I'm considering it), then there's a couple LBT fanfics I may write, the main ones being Cursed and The Dream Effect.
