'Montague. A city of doors, dreams and danger, ruled by a mysterious Queen who keeps a collection of Scarab Children locked in the city’s highest tower. A hub of the Labyrinth, where lands intersect and people can lose themselves with the twist of a handle, the creak of a door hinge.
'Twins Dee and Zet are the latest in a long line who are sent to live in Montague’s lighthouse. The city needs them and their dreams to keep it safe and its thousands of doors to other lands open. But the Queen needs them for a very different reason; a reason that sets brother against brother, imperiling Montague and all who call it home.'
