In this prequel episode from Philip Pullman's His Dark Materials universe, Lee Scoresby -- Texan aeronaut and future friend to Lyra Belacqua -- is 24 years old. The story reveals the origins of Scoresby's friendship with Iorek Byrnison as well as Scoresby's aeronautical career.

After winning his hot-air balloon in a poker game, Scoresby finds himself floating north. On the Arctic island of Novy Odense, Scoresby and his dæmon Hester become involved in a deadly plot involving an oil magnate, a corrupt mayoral candidate, and a hired killer who is Lee's longtime nemesis from the Dakota Country. Forming an alliance with one of the island's reviled armored bears, Scoresby fights to break up the conspiracy.
