In this sequel to The League of Seven (2014), Archie Dent's floundering league is no sooner created before it is ripped apart. Conflicting agendas send Archie and Mr. Rivets on a Septemberist mission to retrieve the mysterious Dragon Lantern, while Hachi and Fergus follow a lead to shed light on the death of Hachi's father. Gratz continues to impress with his alternate 1870s America, which is believable in its innovation and the way it plays with actual events (General Custer is always going to behave like General Custer). The scene is set for a dramatic and challenging conclusion in book three.

This second installment in the intricately plotted steampunk series set in an alternate1870s America opens with Archie dangling twenty-thousand feet in the air on a search for a mysterious lantern, and the action only rises from there. Fans of The League of Seven should be interested in the dark new revelations about Archie's and Hachi's pasts. Helquist's pencil drawings open each chapter.
