Nat is perched on the prow of the Junko as it glides up the Thames one cold, drizzly night. London is to be her home for the next year, and it looks to be a strange and uninviting place after the bright lights and fast pace of Hong Kong. Little does Nat know that she and her dragon-robot, Fizz, are at the start of their second adventure, one that will see them become lost in the high-tech world of one of her father's games and seeking out a long-lost Chinese sword. Secrets that have been kept hidden for decades will be revealed and Nat will learn some startling things about her family, her future, and herself... The second installment of the Nat Walker trilogy.
