City of Dragons # 2: Rise of the Shadowfire

Ever since the battle in Hong Kong, Grace and her friends have been trying to find a way to get to Paris. When Nate suddenly appears and whisks Grace away to the Dragon King's lair, she learns that Daijiang and his underlings are searching for an ancient relic that will let them subjugate the dragons, and Grace needs to find it first!

With Grace's burgeoning Hùnxuè powers, the team must get to Paris and stop Daijiang's plan. But their new ally, Dr. Kim, may not be all she appears, and Daijiang has formidable allies of his own: a strangely familiar accomplice and a terrifying, powerful dragon that could threaten all of Paris.
