Wings of Fire, Savior of Stone

"Three dragonets of different tribes work together to save the ones who haven't seen the sky.
One of night, will save the light.
Another of stone, will claim the throne.
The last will be of clouds, who will make a shroud."

Riverstone has always wondered what it would be like to be an adventurer, exploring new land, coming back a hero from a amazing discovery. She thinks that's what life is all about, and not just sitting at home doing boring things.
When Riverstone was in an egg something catastrophic happened, Cloudwings forced and killed the Stonewings out of their home, so Riverstone and her mom, Geode, out into the dark, scary woods.
