Reddit reviews The Ice Dragon

The WoI&F has a section on the shivering sea that mentions Ice Dragons, and even the magic skeptical Maester who is the imaginary author says there is some credibility to the stories, which is very unusual in the book.

GRRM's version of a children's book, The Ice Dragon, while written pre-ASoI&F, has enough similarities to the story that I can see him introducing the concept in a way that isn't just silly, and he could use it to eliminate all the dragons in one climactic battle. The Others will really be no match for the fire from the sky of Dany's dragons, unless they have something to counter it with, and I don't see the climax being a route on either side.

The Ice Dragon by George R. R. Martin (it's a kids book set in the far past of The Song of Ice and Fire series, and 100% OK for kids).

There sure is!

It's a novella (not sure if he lengthened it or if it's the same story you mention) which I had been sitting on for ages. I really liked it - gorgeous illustrations and it managed to be a very touching story despite its simplicity. Plus the hardcover's dustjacket was a beautiful little poster in reverse. Well worth it IMO, but I love a good children's book. :)

If the Wight Dragon is anything like the Ice Dragon in his previous books, it will breathe frost.
