In this new dark Age, myth and legend has become reality; nothing is quite as it seems.The plague came without warning. Nothing could stop its progress: it's first symptom is black spots at the base of the fingers; an agonising death quickly follows. But this is no ordinary disease . . . Caitlin Shepherd, a lowly GP, is allowed to cross the veil into the mystical Celtic Otherworld in search of a cure; her search takes her on a quest to the end of a land of dreams and nightmares to petition the gods. So Caitlin is humanity's last hope, but she carries a terrible burden: a consciousness shattered into five distinct personalities . . . and one of them may not be human.THE QUEEN OF SINISTER is the latest instalment in Mark Chadbourn's riveting 'Dark Age' sequence: a masterful blend of Celtic myth and Arthurian legend in a modern setting.
