Schwab brings readers back home to the world of multiple Londons. Red London’s original Antari, Kell Maresh has been unable to access his power for seven years (since he, Holland, and Lila fought back the literal darkness of Osaron and Black London). Lila trains him in other ways in the meantime aboard her ship, the Grey Barron. 

Meanwhile, a young child queen, Kosika, takes power in White London and foreshadows much to come in this new trilogy. 

In Grey London, things are much as they once were, although Tes, our newest beloved character, gets to meet Ned Tuttle and experience Grey and White London briefly herself as she fights against a coup planned by an organization calling itself the Hand, hoping to murder Red London’s king, Rhy Maresh. 

More swashbuckling, elemental and Antari magic, and adventures through and across the varied Londons will leave readers eagerly awaiting the next installment.
