Hello everyone. I'm desperately looking for a story I read awhile ago.

It's an AU story about how Sam and Dean were split up as kids. Sam gets adopted by a family and years later has dreams about Dean and realizes he has a brother and wants to find him. Sam and Dean meet later when Dean rescues Sam from a burning house (Dean's a firefighter). The boys later meet Missouri who tells them that the timeline's been mixed up and they're actually supposed to be fighting demons. etc,etc
If anyone can tell me the name or author of this story it would be greatly appreciated.

p.s. if anyone has any other "split up as kids" stories they'd like to recommend i would really appreciate it.

EDIT: Just wanted to let you all know that I managed to find the story I was looking for, but I wanted to thank you all for your help in trying to help me find it. Also, I'm still open to any recs for "split up as kids" stories.

No wincest please.
