The Quite Contrary Colin Pluck

Corvalpluck is a grumpy, middle-aged goblin longing to retire after a long career in espionage. However he has to complete one last mission if the mystical world of Hellfernezia is to survive. His task is to abduct from the human world a girl called Clarissa. As the descendant of an extinct race of Fallen Angels she holds the key to the survival of Hellfernezia. Unaware of her heritage, Clarissa lives in the rural town of Upper Goosemonger. Her mother Pandora disappeared ten years ago under mysterious circumstances, and is believed to be dead. Recently her father Gordon has remarried and now Clarissa has to reckon with a loud-mouthed stepmother Vi and an intrusive stepbrother, Archie.
