After finishing her Encyclopedia of Faeries, Emily Wilde sets out to create a map of the “Otherlands”, the realms of Faerie. She plans to find the nexus, a door to several faerie realms, including the world of her colleague (and exiled faerie king) Wendell Bambleby. When Wendell suddenly finds himself in the crosshairs of his stepmother’s assassins, he and Emily take off to find the nexus, and face Wendell’s aggressors, in the Austrian Alps.

Emily Wilde is a Dryadologist, a scholar specialising in the world of the fae. When she arrives in the Scandinavian village of Hrafnsvik to research the local faery population, she doesn’t intend to befriend the human townsfolk. She is also less than happy to discover that her dashing colleague, Wendell Bambleby, has followed her to the North. Before long, Emily finds herself closer than ever to the world she’s spent her whole life studying, and she finds out just how important friendship can be.
