The Silk Road
Lucy wants an adventure. Dee needs money to help him find his missing parents. When a flaming bird leads them to a hidden road, and the lord of stone offers them a quest, the opportunity for both arises. In a land full of magic, dragons, and demons, all they have to do is befriend a young emperor—which would be a lot easier if he wasn't a royal pain and an angry queen didn't want to destroy him.
With the entitled ruler in tow, Lucy and Dee must find a way home with a mysterious feather and a dragon-whisperer (who looks suspiciously like a hedgehog) their only defence against capture . . . or worse.
