Please help me find this story. It's been driving me nuts!
What I do remember is that Harry has a sibling, but I can't remember if they are twins or not. The other child is deemed BWL and Dumbledore feels that Harry should be given up so they can focus on the other child. James refuses to give up Harry, so while he is gone on a mission Dumbledore talks Lily into giving him up.
I don't remember what Dumbledore and Lily told James, but I know there was a divorce involved. Harry ends up getting hurt in school and that is how he finds out about Lily and James. Lily tries to be all nice and explain to Harry what happened. I want to say James and Severus end up together. I may be wrong though.
Please help!
