Son of Lightning - Descendants of Robin Hood, #3

There's two sides to every story. Jack's victory over Sorcerer Gisborne is bittersweet as he grieves Nick's death at the hands of the all-consuming Sorcerer. But unknown to Jack, a fragment of his best friend survived. Buried in his own mind, Nick struggles desperately to maintain his identity as he sinks under Gisborne's control. Determined to prevent any further deaths, Jack sets off to rescue Natanian from the monsters who kidnapped him.
But what he discovers will set off a chain of events that threatens to end only one way-with the nations destroyed and Gisborne as the sole victor. In this thrilling finale to the Descendants of Robin Hood series, Jack is faced with a fateful choice-save his nation, or save his friends.
