nickngreg | Help?

Hi I'm a lurker here hahaha. I was wondering if anyone can help me find this fic? Well from what I remember Greg was about seven when his parents died and he was left in the care of his aunt and uncle who have many kids. While in a bookstore he meets Nick who I think is nine. Anyways When his aunt and uncle heard the news about Greg's parents the uncle takes Greg and his stuff to the car. Greg needs to pee and they stop at the mall. When Greg is finish he finds that his uncle had left him. He is about to be snatched up by some rapist dude when Nick saves him. Nick's parents adopt Greg and they grew up as "brothers" but they never felt that way about each other. Then Nick gets put in that grave and everyone finds out.

Yeah pretty detailed huh? Yeah I really want to find it. So can you guys help me? Thanks!!
