Lucifer's daughter, the Winchesters's "sister"A Supernaural Fan-Fiction

The Winchesters find out that their friend Skyler is dead when her 2 month old daughter is dropped off at the motel room that they are in.
The baby will be in the plot of all the episodes some how.
The boys already know who Lucifer is and who Crowley is, there is this half Angel named Lawrence and he is the son of Michael and he is the one who killed Skyler.

I suck at descriptions.

I don't own Supernaural or the characters I only own some of the plot and the characters Skyler,Lawrence and Beth maybe some other characters but their not in the story yet.
