Well, if you don't mind a pretty emo Harry, nothing. Well, that many feel (myself included) that many/all of his stories are roughly all the same thing with the names and places changed. Oh, and glacial character development (it happens in eons instead of chapters).
Though I might be unduly harsh, it has been a while since I've read anything by Kinsfire. On the other hand, an author has to really stand out in a bad way for me to mentally blacklist them (or more accurately, have titles/summaries that routinely interest me and then manage to punish my interest, Pavlovian conditioning works on me).
