Read the first 3. I don't understand what happened to the rabbit familiar between chapters 2 and 3. If he was supposed to fuse Jinx/the dragon and was just there to help form/test their relationship, or you just suddenly dropped him, I couldn't tell what was happening there.
I liked your descriptions of character actions. Jinx had a fun personality. There's potential here, I just don't understand what happened to the rabbit boy you set up.
