Now in paperback!

Morgan Enni has things to do. A science prodigy in a university full of mage-scientists, she’s notable for having no magical ability, which only increases her ambition and drive to prove herself. Her research has the potential to devastate every aetherworker in the galaxy and shake the crumbled foundations of the Stavenger Empire. It's no wonder she can't find anyone who wants to listen to her, much less fund her expedition.

But Morgan is stubborn, and eventually her work catches the attention of a group of rebels, who hope it might turn the tide in their favour. When they try to recruit the young scientist, they get much more than they bargained for. Morgan Enni has secrets of her own.

Set in the world of Aetherbound, E.K. Johnston continues to entwine Arthurian myth and the history of North Atlantic fisheries in a clever, character-driven space fantasy.
