'After the tumultuous events that saw the defeat of the heinous blood-drinking society of immortals, Immortalis Serapsis, Artemis Devereaux flees the United Republic of Britannia in her dirigible, Taygete. Alone, she travels the world searching for clues to the whereabouts of her undead husband. Her journey brings her to Terra Australis, ostensibly to attend the Great Southern Scientific Fair, but her arrival in this land heralds a change of fortunes. Old enemies resurface with their sights set on her capture, and the long-awaited reunion with Nathaniel is brutal. With her life in danger, Artemis must rely on new, untested friends while she waits for her sister and compatriots to fly in from New Londinium. However, the strange yet beautiful Terra Australis holds dangers and challenges for the entire gang, with life-changing and sometimes devastating consequences.' (Publication summary)
