From National Book Award finalist Randy Ribay comes a gripping new chapter—starring Avatar Roku—in the New York Times bestselling Chronicles of the Avatar series, set in the world of Avatar: the Last Airbender and The Legend of Korra.

A young Avatar Roku has only just commenced his training at the Southern Air Temple when his erstwhile friend, Prince Sozin, requests his aid in preventing the Earth Kingdom from claiming a remote Fire Nation island. Despite his inexperience, Avatar Roku slips away with the help of an irritating young Airbender named Gyatso. As the reluctant companions delve deeper into their wayward mission, they begin to realize that even greater threats lie ahead. Plagued by self-doubt but eager to prove himself, Roku fights for his life and the lives of others while ensuring that the hidden secret of the island doesn’t fall into the wrong hands.

This searing fifth installment in the Chronicles of the Avatar series explores the beginning of Roku’s journey from privileged Fire Nation noble to the powerful but indecisive Avatar whose hesitancy may ultimately pave the way for the Hundred Year War.
