I am desperately trying to find this fic. I must have read it 5 years ago by now, but the description started off something like " Nathan and Haley along with her young son..." And her sons name is Sam, and she used to be married but she divorced and moved to tree hill. Nathan moves in next door, and they begin to date. Deb died of cancer and haley hides the fact she is a survivor and eventually get breast cancer again while carrying their child.
