I love this fic! Its a refreshing idea, bits of absurd humor to keep one going. I haven't finished it yet, its boring that way. I keep reading a couple of chapters every now and then, as a sort comfort-read.
There's something sad to think about the whole underlying idea actually. My guess as to why Harry became a dragon is that he developed this defensive mechanism to survive the Dursley treatment- his magic sort of morphing himself to protect him guided by the innocent ideas of a then primary school Harry.
This is what keeps me re-visiting this fic. Whenever I'm particularly low due to life troubles I search for a dose of some 'sheer acceptance and evolving' and laugh it off.
I'd rate it a 4.25/5
