Wow that's got a really interesting premise.
I like it, I really enjoyed reading it and loved the moral dilemma that the girls faced, choosing the right option in the end.
Though I do feel sorry for Summmerscale- the original dragon.
I was waiting for the part where Razelle said that Sunnerscale wasn't her usual human hating self because after the rock fall, Razelle had healed her wounds, proving that not all humans are bad, therefore changing her opinion of them and making her more tolerant and accepting of them.
Is this just a short story or a part of a larger story?
