Eddie Drood, the last of his magically-inclined family, must race against time to find his relatives after their ancestral home is destroyed and they are seemingly killed. His objective is to locate his family, who have been displaced to an alternate Earth via a dimensional engine, while confronting the forces responsible for the destruction and the potential threat of a doppelgänger Hall. The narrative framework appears to be first-person, with Drood recounting his experiences and motivations.

The premise sets up a fast-paced urban fantasy adventure, typical of Simon R. Green's style, focusing on a lone protagonist with a unique heritage battling supernatural forces. The narrative structure, driven by a first-person account, suggests an immediate and personal connection to the unfolding events. Readers can anticipate a blend of action, mystery, and the introduction of fantastical elements as Drood navigates the consequences of his family's displacement. The story likely explores the burden of legacy and the lengths one would go to for family.
