Why is the dragon the only fantasy creature in the Chinese zodiac? Maybe it's because dragons aren't a fantasy after all...

Moli has never seen a dragon, but she'd imagined one many times. Following the death of her father, a museum curator and historian, her need to escape from the real world has never felt so acute.

Travelling from China to London to attend the funeral, Moli takes the opportunity to visit her father's last exhibition, "The Lost Dynasty of Rouran". The trip reveals Moli's connection to an ancient khanate and, unexpectedly, opens the door to another realm. This is just the beginning of an adventure that takes her travelling through time to a world of shamans, rituals, conqueror worms, dragon chariots and even a confrontation with the world's greatest foes.

To save humanity, Moli and an unlikely quartet of heroes are sent back in history, but can they outrun a fate worse than death? And where does reality end and magic begin? Enter a world where everything is possible...
