I didn't love this fic, but I finished reading it so it means I didn't think it's bad. I liked the original characters (the non-reapers are OC, no?) which is rare, I generally don't welcome OC that well.
I just think it could have been better. And Brian was barely there. Many things felt rushed (seeing that it was for nano probably that's a given). I remember another death fic (also post season 1) I read, quite a long one. It sucked in general and I didn't finish it, but one tiny part at the beginning was truly heart wrenching, and that's also what's missing in this Reaper Boy fic, because I didn't feel sad reading this. Except for the too short part about Knox dealing with Curt's death. I liked Knox.
