From publisher blurb:
The ruins of Manhattan – better known as Madhaven – are a place of madness, ghosts and monsters. For some the ruins offer the promise of ancient secrets, power or treasure. For the mutants who inhabit the shattered landscape, it is truly a haven. For the Knights of the White Rose it is a hiding place. For many others, however, Madhaven is their doom.
